PROBLEM TO BE SOLVED: To obtain excellent diffusing reflection by providing a polarizing plate which is arranged outside a liquid crystal cell, a mirror surface reflecting plate which reflects incident light, and a film which has two kind of extremely small areas having different refractive indexes. SOLUTION: A light control film 1 is a film which functions to scatter light made incident from a specific direction. In this case, a light control film which scatters light that is made incident in the perpendicular direction to the light control film 1 is used to scatter light reflected by a reflection electrode 4, thereby enabling diffusing reflection. As this light control film 1, a film is used which is formed by irradiating a mixture of two kind of ultraviolet-ray setting high polymers with ultraviolet rays. This film structured by laminating layers of high polymers having two kind of refractive indexes. The reflecting electrode 4 is formed of metal such as aluminum. Then STN liquid crystal 20 is applied with the potential difference between a transparent electrode 3 and the reflecting electrode 4. According to the applied voltage, the STN liquid crystal 20 shows different optical characteristics, which are utilized to make a display. |
