20080231777LIQUID CRYSTAL APPARATUS, COLOR FILTER SUBSTRATE, AND ELECTRONIC APPARATUS - A liquid crystal apparatus includes a pair of substrates. The pair of substrates includes a liquid crystal layer disposed therebetween, and a two-dimensional array of pixel regions each including a transmissive display region and a reflective display region, the transmissive display regions of different pixel regions having areas different from one another. One of the substrates has a plurality of color filter layers provided in correspondence with the pixel regions, a reflective film provided over the color filter layers, and an overcoat film covering the reflective film. Among the pixel regions including the transmissive display regions having different areas, a pixel region including a transmissive display region with a large area has a color filter layer with a thickness larger than that of a color filter layer provided in a pixel region including a transmissive display region with a small area.09-25-2008
20080273150Liquid crystal display device, substrate assembly for liquid crystal display device, and electronic apparatus - A liquid crystal display device having a first sub pixel and a second sub pixel. The first sub pixel corresponds to a first color layer having a first color. The second sub pixel corresponds to a second color layer having a second color. The first and second sub pixels each have a rectangular shape that includes a pair of longer sides. A first reflective region and a second reflective region, in which first and second reflective films are disposed, each extend across the first sub pixel and the second sub pixel respectively between the longer sides. A first transmissive region and a second transmission region, in which the reflective films are not disposed, each extend entirely across the first sub pixel and the second sub pixel respectively between the longer sides. An area of the first reflective region is different from an area of the second reflective region.11-06-2008
