  • Patent number: 9864226
    Abstract: In a liquid crystal display device, there is provided a liquid crystal display panel in which a TFT substrate and a counter substrate are bonded together by a sealing material, with a liquid crystal sandwiched between the substrates. Further, a front window with a black border print formed in the periphery is bonded to the liquid crystal display panel by a UV curable resin. The liquid crystal is filled by a drop method. The thickness of the TFT substrate and the counter substrate is reduced to about 0.2 mm by polishing. An inner end of the black border print of the front window is inside an inner end of the sealing material, to prevent the counter substrate of the liquid crystal display panel from being deformed by stress generated in the curing of the UV curable resin, thereby preventing yellow discoloration in the periphery of the display area.

  • Patent number: 9110336
    Abstract: Columnar spacers are formed on a TFT substrate where a TFT circuit layer is formed. The TFT circuit layer has a TFT and a pixel electrode. A spacing between the TFT substrate and a counter substrate having a color filter, a black matrix, and an overcoat film is controlled by columnar spacers. The columnar spacers are inserted into an overcoat film formed on the counter substrate. Thus, the counter substrate and the TFT substrate are protruded inward. The substrates protruded inward are unlikely to be deformed. When an external pressure is applied or the front window or the like is bonded to the liquid crystal display panel with resin, the counter substrate is unlikely to be deformed by a stress applied by shrinkage on resin curing. Moreover, the number of columnar spacers can be properly set, thereby preventing the occurrence of low-temperature air bubbles.

  • Publication number: 20150212370
    Abstract: Light emitted by a backlight can be prevented from leaking through a chamfered portion of a front window of a liquid crystal display device. An upper polarizing plate is bonded over the counter substrate, and a front window is bonded over the upper polarizing plate with a UV-curable resin adhesive. The front window is chamfered and a light shielding member is formed on the chamfered portion. The UV adhesive exists between the chamfered portion and the surface of the upper polarizing plate or the counter substrate, and an outer end of the polarizing plate exists at a point outer than an outer end of the front window. Since the light shielding member for the chamfered portion is formed, light from the backlight does not penetrate from the chamfered portion. Thus, light leakage at a periphery of a screen can be prevented even when the view angle is large.

  • Patent number: 8961731
    Abstract: In a three-dimensional image display device using a liquid crystal parallax barrier panel, a liquid crystal display panel is first roughly aligned with the liquid crystal parallax barrier panel using an alignment mark. Subsequently, a white pattern for two pixels is formed in the center of a screen. When an observer's eyes are brought close to the screen, a blue pattern is generated in the center, and a white pattern is generated on both sides of the blue pattern. The relationship between a width d1 of the blue pattern and a width d2 of the white pattern is d1=2d2, and the tilt of the blue pattern is set in a predetermined range, so that necessary alignment accuracy can be secured.

  • Patent number: 8953123
    Abstract: In a liquid crystal display device having a front window, light from a backlight is prevented from leaking through chamfered edges of the front window. An upper polarizing plate is formed on an opposing substrate and a light shielding material is formed abutting on an outer edge of the upper polarizing plate. Edges of the upper polarizing plate are located inward of edges of the front window. The upper polarizing plate and the front window are bonded with a boding material including an ultraviolet curable resin. The ultraviolet curable resin also lies over the light shielding material. Chamfers are formed in the front window and the ultraviolet curable resin does not adhere to the chamfers of the front window. By this structure, light from the backlight is prevented from entering the internal part of the front window through the chamfers of the front window and light leakage is prevented.

  • Patent number: 8908118
    Abstract: In a liquid crystal display device enabling three-dimensional display using a liquid crystal lens, both mechanical strength and a liquid crystal lens effect are satisfied. The liquid crystal lens is bonded onto an upper polarizing plate of a liquid crystal display panel with a bonding material. The liquid crystal lens includes an upper substrate, a lower substrate and a liquid crystal layer sandwiched therebetween. The upper substrate of liquid crystal lens has a thickness larger than a total of the thickness of the lower substrate of the liquid crystal lens and the thickness of the liquid crystal display panel. Thereby, it is possible to realize a liquid crystal display device satisfying both the mechanical strength and liquid crystal lens effect.

  • Patent number: 8599342
    Abstract: A liquid crystal display panel including liquid crystal sandwiched between a pair of substrates is prepared. A light-transmitting reinforcing plate is prepared. A photocuring resin is provided between the liquid crystal display panel and the reinforcing plate. Light is irradiated to a side surface of a laminated body constituted of the liquid crystal display panel, the reinforcing plate and the photocuring resin. The photocuring resin is arranged to face the liquid crystal in an opposed manner. The light is allowed to advance to the inside of the photocuring resin from an edge portion of the photocuring resin. The light is allowed to advance to the inside of the reinforcing plate from an edge portion of the reinforcing plate, is propagated in the inside of the reinforcing plate, and is irradiated to the photocuring resin from the reinforcing plate at a position away from the edge portion of the reinforcing plate.

  • Publication number: 20130299082
    Abstract: A liquid crystal parallax barrier panel and a liquid crystal display panel are held by vacuum-holding, and aligned so as to be laminated via an adhesive. After the lamination, the vacuum-holding is released. Then lamination of the liquid crystal display panel and the liquid crystal parallax barrier panel is finely adjusted, and the adhesive is temporarily cured by radiating ultraviolet rays. The adhesive is primarily cured and further thermally cured by ultraviolet rays to complete manufacturing of a three dimensional display device. Release of the vacuum-holding before temporary adhesion using ultraviolet rays allows suppression of deformation of a TFT substrate owing to the vacuum-holding as well as the gap unevenness and the color shading of the liquid crystal panel.

  • Publication number: 20130284350
    Abstract: An ultraviolet-curable resin is formed over a touch panel, and a liquid crystal display panel is bonded to the touch panel. Subsequently, an ultraviolet-curable resin is formed over the touch panel, and a front window is bonded to the touch panel. While the ultraviolet-curable resin is cured unevenly due to a black-frame print made around the periphery of the front window, the touch panel and the counter substrate of the liquid crystal display panel are already bonded together at this time. This prevents the uneven cure of the ultraviolet-curable resin from distorting the counter substrate alone. As a result, it is possible to avoid unevenness of the gap between the counter substrate and the TFT substrate of the liquid crystal display panel and the resulting yellowing around the periphery.
