Reflection type color liquid crystal display device having sub-pixels for increasing luminance, and a light scattering film including color filters for the sub-pixels and manufacturing method thereof

摘要

A reflective color liquid crystal display device capable of increasing the luminance of display without decreasing color purity. The display device displays a color image formed based on unit pixels each of which has sub-pixels corresponding to primary colors by using extraneous light, which has a liquid crystal layer varying a state of light transmitted therethrough, a reflection layer reflecting light which is incident thereon, a transparent electrode layer and a pixel electrode layer for applying electric field to the liquid crystal layer for each of the sub-pixels in accordance with an image to be displayed, a color filter layer having portions that perform coloring of the primary colors for the light to be transmitted (or the light having transmitted) through the liquid crystal layer in correspondence with the sub-pixels. The unit pixel also has a sub-pixel for increasing luminance, the additional portion transmitting light components of predetermined wavelengths from the light to be transmitted (or the light having transmitted) through the liquid crystal layer.
