Abstract:
1. A liquid crystal display device for displaying an image and including a plurality of pixels, the liquid crystal display device comprising: a first substrate, a second substrate, and a liquid crystal layer interposed between at least the first substrate and the second substrate; a pixel region corresponding to one of the plurality of pixels; wherein the pixel region includes a reflection region having light reflectivity and a transmission region having light transmissivity; wherein light from the reflection region and transmitted light from the transmission region are utilized in displaying the image; wherein the reflection region of the pixel region includes a reflection layer provided at least in the reflection region; wherein the transmission region of the pixel region includes a transparent pixel electrode provided in at least the transmission region; wherein the liquid crystal layer is substantially thicker in the transmission region than in the reflection region; wherein the reflection layer is in electrical communication with the transparent pixel electrode, and is also in electrical communication with a transistor corresponding to the pixel region; wherein an upper surface of the reflection layer has a concave/convex shape; and wherein the reflection layer is electrically connected to a drain of the transistor via an opaque metal layer.
