  • Publication number: 20040051827
    Abstract: In a display device 100, a reflective polarizer 110, a polarizer 120, a retarder 130, a liquid crystal panel 140, a polarizer 150, and a backlight 160 are disposed sequentially from the viewing side. When the liquid crystal panel 140 is set in a light blocking state or the backlight 160 is set in an unlit state, the reflection of an outside light “O” turns the display screen into a mirror state. When the backlight 160 is set in a lit state to drive the liquid crystal panel 140, a transmitted light “T” allows a particular display screen to be visually recognized.

  • Publication number: 20020163614
    Abstract: A liquid crystal device 1, that is, an electrooptic device, has a second electrode 11 provided so as to oppose a first electrode 10, and a liquid crystal provided between the first electrode 10 and the second electrode 11. This liquid crystal device 1 further has a first substrate 2 on which the first electrode 10 is provided and a wire 14 which is formed on the first substrate 2 and is electrically connected to the second electrode 11 at a conduction position 4a. Since the wire 14 extends inside the conduction position 4a, the picture frame region that is outside a sealing material 4 can be decreased.

  • Publication number: 20020118325
    Abstract: A liquid crystal device 1 includes a liquid crystal 23 arranged between a first substrate 2 and a second substrate 3. The liquid crystal device has a reflecting conductive film 18 formed on the first substrate 2, a light transmitting metal oxide film 19 laminated on the reflective conductive film 18 so that the edges 34 thereof are in contact with an underlying film 35 or the first substrate 2, and an illumination device 25 for irradiating the liquid crystal 23 with light from outside the first substrate 2. Since the edges are present around the reflective conductive film 18, the area of a light reflecting region contributing to reflection is not changed even when the position of the reflective conductive film 18 is deviated in the transverse direction.

  • Patent number: 6437846
    Abstract: A liquid crystal display device comprising a flexible substrate of, for example, plastic film. At least one edge of a pair of polarizers (9, 10), which are arranged on the liquid crystal display is extended to the region of an electrode terminal (7) which is formed on a substrate (2). By increasing the mechanical strength of the electrode terminal (7) of the liquid crystal display, terminal electrode cracks caused by mechanical stress that increase during the manufacturing process and incorporation into electronic calculators can be decreased and further, a liquid crystal display with a decreased number of disconnections and high reliability can be realized.

  • Patent number: 6369865
    Abstract: A liquid crystal (L) is sealed in a cell gap to be formed between a pair of transparent substrates (8a), (8b) to constitute a liquid crystal display device (2). Another plastic film (17b) of an input device (3) in which one plastic film (17a) is pressed by a pen (21), etc. under the instruction of the positional information is stacked on the liquid crystal display device (2) across a transparent elastic member (4), and a liquid crystal display device (1) is formed thereby. Both the descriptive durability and the input touch of a film-film type input device are improved at the same time. When the transparent substrates (8a),(8b) are formed of flexible material, the external force is prevented from being applied to the flexible transparent substrates (8a),(8b) easy to be locally deformed by absorbing the external force to be applied to the input device (3) by the transparent elastic member (4).

  • Publication number: 20020008815
    Abstract: A liquid crystal device has a configuration including substrates 200 and 300 bonded to each other with a sealant 110 and a liquid crystal 160 enclosed in the gap therebetween. Common electrodes 214 are provided on the inner face of the substrate 200, whereas an underlying film 301, a reflective film 302 composed of a silver alloy, a protective film 303 covering the reflective film 302, and segment electrodes 314 are provided on the inner face of the backside substrate 300. Since the protective film 303 suppresses the crystal grain growth of the reflective film 302 at a high-temperature treatment, a decrease in reflectance is avoided. A lead 350 comprises a laminate of a reflective conductive film 352 having a crystal grain size which is larger than that of the reflective film 302 and a transparent conductive film 354 which is formed by patterning the same layer as the segment electrode 314.

  • Publication number: 20020008681
    Abstract: The liquid crystal display device has a structure having substrates 200 and 300 adhered to each other by a sealing material 110 with a predetermined gap therebetween and having liquid crystal 160 enclosed in the gap. On an opposing surface of the substrate 200, transparent electrodes 214 are formed, and on an opposing surface of the substrate 300, segment electrodes 314 are formed. The common electrodes 214 are connected to wiring 350 formed on the substrate 300 via conductive particles 114 mixed in the sealing material 110, and the wiring 350 are each a laminated film of a transparent conductive film 354 composed of the same conductive layer as that of the segment electrode 314 and a low-resistance conductive film 352 composed of a low-resistance material, such as chromium, having a resistance lower than that of the transparent conductive film 354. However, the low-resistance conductive film 352 is formed at an area other than the portion connecting with the conductive particles 114.

  • Patent number: 5687465
    Abstract: A liquid crystal display element utilizing flexible gas barrier films decreases poor display performance caused by bubble formation. This decrease is achieved by reducing the permeation of gas and water vapor from the gas barrier films into substrates by devising the structure of the element and the configuration in which the element is mounted. Specifically, edges of the substrates forming the liquid crystal display elements are sealed. Additionally, the gas and water vapor saturation solubilities of the liquid crystal material is controlled to improve resistance to bubble formation. The liquid crystal display elements can also be subjected to and/or stored in a reduced pressure. Electronic equipment incorporating liquid crystal display elements can include a guard plate having a minimum thickness and/or spacing from the display elements.
