  • Publication number: 20060262240
    Abstract: The present invention prevents a frame-like luminance difference generated in a portion which surrounds a light transmissive region. In a pixel region formed on a substrate, a first pixel electrode formed of a light transmissive conductive layer is formed in one light transmissive region which is formed by partitioning the pixel region and a second pixel electrode formed of a non-light transmissive conductive film is formed on the other light reflective region. The first pixel electrode is positioned as a lower layer with respect to an insulation film. A hole is formed in the insulation film in a region corresponding to the light transmissive region so as to expose the first pixel electrode. The second pixel electrode is formed on a light reflective region of the insulation film. Light shielding is performed at a portion corresponding to a side wall surface of the hole formed in the insulation film.

  • Publication number: 20060152642
    Abstract: Even when gate lines are pulled around at both left and right picture frame regions, it is possible to prevent a gate wiring pattern which is constituted of the gate lines and gate-line pull-around lines and a storage wiring pattern which is constituted of storage lines and a common line which connects storage lines each other from getting over each other. The gate lines GL1, GL2 are pulled around by the gate-line pull-around lines GLL1, GLL2 in both left and right picture frame regions. The common lines B2, B3 which connect the storage lines STL each other are formed at both left and right picture frame regions. Further, the gate wiring pattern which is constituted of the gate lines GL1, GL2 and the gate-line pull-around lines GLL1, GLL2 and the storage wiring pattern which is constituted of the storage lines STL and the common lines B2, B3 do not cross each other.

  • Patent number: 6788364
    Abstract: Light leakage within pixel area is prevented. A liquid crystal display device includes a light reflection area forming pixel electrode and a reflection film in one portion of a pixel area on a liquid crystal side face of one substrate oppositely arranged through the liquid crystal. A light transmission area forms the pixel electrode in another portion. The pixel electrode as the reflection film is formed on the upper face except for an opening portion of an insulating film. The opening portion is formed in a light transmission area. The opening portion of the insulating film has a fan-shaped taper from the substrate side to the liquid crystal side on the side wall face of this opening portion. At least one portion of this taper is not covered with the pixel electrode used as the reflection film, but is exposed. The insulating film has a light absorption property in at least the taper portion.
