  • 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.

  • 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: 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.
