ABSTRACT:
To provide a reflector using cholesteric liquid crystals arranged in a structure for reducing thickness, and a transflective liquid crystal display device including the reflector.[Solving Means] In a transflective layer18,pitch areas18R,18G, and18B are formed within a plane of one dot, and color filters30R,30G, and30B of respective colors are formed in respective dots in order to form one pixel. Therefore, the transflective layer18can be formed thin, and can reflect white light by a mixture of the colors of light reflected by the respective pitch areas18R,18G, and18B in one dot. In addition, the pitch areas18R,18G, and18B can pass the complementary colors of the colors corresponding to the pitch areas18R,18G, and18B, so that, even by color mixture, white light can be transmitted in one dot. Therefore, it is possible to perform a color displaying operation for each pixel through a color filter layer30based on reflected light and transmitted light close to these white lights.
