Abstract:
An ECB type color liquid crystal display device for one of a reflection-type and transmission-type liquid crystal display, said ECB type color liquid crystal display comprising:a transparent electrode and an orientation layer sequentially formed on an inner side of each of a pair of transparent substrates opposed to each other through an STN type liquid crystal layer, and a pair of polarizing plates opposed to each other through the transparent substrates and the liquid crystal layer;a semi-transmissive scattering layer provided on an outer side of at least one of said pair of polarizing plates, said semi-transmissive scattering layer disposed on a back surface side of at least one of said pair of polarizing plates, the back surface side being an opposite side of a display surface side; anda backlight provided on a back surface side of the semi-transmissive scattering layer,wherein an angle made by the orientation layer of the transparent substrate arranged on the semi-transmissive scattering layer side and an absorption axis of the polarizing plate adjacent to the transparent substrate is about 70 to 90 degrees, and wherein an angle made by the absorption axis of the polarizing plate and an optical axis of the semi-transmissive scattering layer is about -40 to -70 degrees.
