Abstract

PURPOSE: To improve the lighting effect with the built-in lamp in the nighttime by disposing a reflector on the back of a transparent material plate mixed or coated with light storing material 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 18 on the back sede, a reflecting face layer 22 is formed by providing undulations 32 on the front of a transparent material plate (e.g., acrylic resin plate) 21 added with light storing material 23 and vapor depositing aluminum or other on the back side and this is used as a reflecting plate. In the nighttime, a built-in lamp 20 is lighted and the entire part of the display body is brightly lighted while exciting the light storing material 23 with the light thereof. Even after putting out of the lamp 20, the lighting may be continued for a while by the light emission of the light storing material.
