  • Patent number: 7182877
    Abstract: A method is provided for manufacturing an electro-optical device, in which fine scratches or cracks can be removed by etching without damaging wiring, an electro-optical device, and an electronic apparatus. According to the method, a liquid crystal panel used in an electro-optical device is cut as a single product. Then, before an IC mounting step, in a state of the single product liquid crystal panel, a wet etching is performed on the cut faces and edges of the first and second substrates to remove fine scratches or cracks from the cut faces and edges of the substrates. At this time, wiring portions, IC mounting terminals, substrate mounting terminals, and alignment marks, which are formed on the protruding region, are covered with a protection layer.

  • Patent number: 7092050
    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: 6927818
    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: 6831717
    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.
