Abstract
PURPOSE: To improve lighting effect with the built-in lamp in the nighttime by disposing a reflector on the back of a transparent material plate provided with undulations on its front and back surfaces with the roughness of the back being made finer than that of the front to form a reflecting plate and forming the light receiving type display device by using this.
CONSTITUTION: In the light receiving type display device formed by sealing liquid crystal 14 between panel glasses 13, 16 provided with electrodes 19, disposing polarizing plates 12, 17 on both sides thereof and disposing a reflecting plate on the back side, undulations are formed on both surfaces of a transparent material plate (e.g., acrylic resin plate) 21 with the back undulations 32 being made finer than the front undulations 31 and a reflecting face layer 22 is formed on the back surface through vapor deposition of aluminum or other and this is used as a reflecting plate. In the nighttime, a built-in lamp 20 is lighted and the light thereof is refracted upward by using the undulations 32 on the back surface, whereby the entire part of the display body is brightly lighted.
