Liquid crystal display device
First Claim
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 switching device corresponding to the pixel region; and
wherein an aperture is defined in the reflection layer, and a metal layer is located in at least part of the aperture below the reflection layer as viewed from above.

Abstract
A liquid crystal display device includes a first substrate; a second substrate; a liquid crystal layer interposed between the first substrate and the second substrate; a first polarizer provided on a surface of the first substrate which is on the opposite side to the liquid crystal layer; a second polarizer provided on a surface of the second substrate which is on the opposite side to the liquid crystal layer; a first phase compensation element provided between the first polarizer and the liquid crystal layer; and a second phase compensation element provided between the second polarizer and the liquid crystal layer. A plurality of pixel areas are provided for display. The first substrate includes at least one transmissive electrode, and the second substrate includes a reflective electrode region and a transmissive electrode region in correspondence with each of the plurality of pixel areas.
