Liquid crystal display device having misaligned reflectors
View Patent ↗A liquid crystal display device includes a pair of substrates composed of a first substrate and a second substrate, which are disposed opposite to each other with a liquid crystal layer interposed therebetween; a plurality of pixels arranged in a matrix; reflective layers that are provided on the second substrate and reflects incident light from the first substrate side; a plurality of sub-pixels constituting each of the plurality of pixels; color filters on which colored layers having different colors are arranged, each of the colored layers corresponding to each of the sub-pixels; and an illumination unit provided at an outer surface side of the second substrate. The liquid crystal display device is a transflective liquid crystal display device for displaying images through a reflective region and a transmissive region, which are provided in each of the sub-pixels. The reflective region of each sub-pixel is a region for black and white display or monochrome gray-scale display, the transmissive region is a region for color display in the pixels, and reflectance of the reflective region of each sub-pixel is different for each of the sub-pixels having different colors.
1. A liquid crystal display device comprising:
a pair of substrates composed of a first substrate and a second substrate, which are disposed opposite to each other with a liquid crystal layer interposed therebetween;
a pixel including a plurality of sub-pixels;
reflectors provided in between the second substrate and the liquid crystal layer and that reflect incident light from the first substrate side, the reflectors arranged in a row direction and in a column direction, each reflector having two opposite terminal ends that are parallel to the row direction and that are perpendicular to the column direction, each opposite terminal end of each reflector being out of alignment in the row direction with the opposite terminal ends of adjacent reflectors;
a color filter including red, green, and blue colored layers in a completely non-overlapping condition with the reflectors in plan view; and
a reflective region and a transmissive region provided in each of the sub-pixels, the reflective region of each sub-pixel being in a non-overlapping condition with the color filter for black and white gray-scale display or monochrome gray-scale display, the transmissive region of each sub-pixel being in an overlapping condition with the color filter for color display in the pixel.
2. The liquid crystal display device according to claim 1 , wherein an area of the reflective region of each sub-pixel is different for each of the sub-pixels having different colors.
3. The liquid crystal display device according to claim 2 , wherein a light shielding portion overlaps the reflective region of each sub-pixel, and an area of the reflective region is different for each sub-pixel due to an area of the light shielding portion being set to be different for each sub-pixel.
4. The liquid crystal display device according to claim 3 , wherein the light shielding portion is composed of a light shielding film provided between the sub-pixels or is composed of a wiring line.
5. The liquid crystal display device according to claim 1 , wherein the colored layers have different colors corresponding to red (R), green (G) and blue (B), and the reflectance of the reflective layers of the sub-pixels goes from high to low in the order of a green (G) sub-pixel, a red (R) sub-pixel, and a blue (B) sub-pixel.
6. An electronic apparatus comprising the liquid crystal display device according to claim 1 .
