Liquid crystal display device and electronic apparatus having color filter layer comprising cholesteric liquid crystal films and pigmented films |
摘要 |
The invention provides a transflective liquid crystal display device in which the brightness in a transmissive mode is enhanced to have excellent visibility. A liquid crystal display device of the present invention has an upper substrate and a lower substrate opposing each other and liquid crystal held between the upper substrate and the lower substrate. A transflective layer including cholesteric liquid crystal films are disposed above the lower substrate. A backlight is also provided. Retardation layers and polarizers are disposed outside the upper substrate and the lower substrate, respectively, in that order from the substrate sides. A pigmented color filter layer including pigmented films underlies the transflective layer to transmit light of the same color as that of light selectively reflected at the respective cholesteric liquid crystal films.
