Abstract

PURPOSE: To eliminate the light/dark difference of a display device by using a fine reed screen type sheet, provided with many projection streaks which are parallel at fine intervals, as a reflecting plate. CONSTITUTION: The fine reed screen type sheet 3a provided with many projection streaks 2, which are parallel at fine intervals, on at least one surface of a transparent sheet 1 is used as the reflecting plate which is arranged between a liquid crystal element or display 5 and a light source 5. For example, a plane reflecting mirror 4 is provided, a cold cathode-ray tube 5 as a light source is arranged off right behind the sheet, and liquid crystal 6 is arranged right above it. Consequently, the light from the light source is uniformly diffused without being attenuated to irradiate the whole liquid crystal entirely.
