Abstract
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.
