Abstract
A liquid crystal display includes a pixel comprising first to fourth sub-pixels capable of respectively displaying red, green, blue, and white. Each of the sub-pixels comprises a reflective area and a transmissive area. The liquid crystal display includes a first laminated member provided on a first substrate and a second laminated member provided on a second substrate. The first laminated member comprises a first retardation plate and a first polarizer. The second laminated member comprises a second retardation plate, a diffusion member for diffusing light, and a second polarizer.
Claims9
A liquid crystal display, comprising:
- first and second substrates;
- a liquid crystal layer interposed between the first and second substrates;
- a pixel comprising first to fourth sub-pixels capable of respectively displaying red, green, blue, and white, each sub-pixel of the first to fourth sub-pixels comprising a reflective area and a transmissive area arranged in an adjacent area to the reflective area in a horizontal direction;
- a switching element provided on the first substrate to correspond to each sub-pixel;
- a reflective film provided in the reflective area above the switching element with an insulating film interposed in-between;
- a pixel electrode provided in the reflective area and the transmissive area above the reflective film with an insulating film interposed in-between;
- a red filter, a green filter, a blue filter, and a white filter provided on the second substrate to correspond to the first to fourth sub-pixels, respectively;
- a first laminated member provided on an opposite side of the first substrate with respect to the liquid crystal layer, the first laminated member comprising a first retardation plate and a first polarizer;
- and
- a second laminated member provided on an opposite side of the second substrate with respect to the liquid crystal layer, the second laminated member comprising a second retardation plate, a diffusion member for diffusing light, and a second polarizer.
