Claims

[Claims for Utility Model Registration] A liquid crystal cell and a light guide disposed below the liquid crystal cell, having a light diffusion layer formed on the upper surface and increasing in thickness as the lower surface faces both sides. and a light source disposed on the side of the light guide, the slope provided on the lower surface of the light guide,
A notch is connected to the horizontal lower surface of the light guide through a curved portion in front of the side surface thereof, and a notch is provided along both side edges of the lower surface of the light guide to form a stepped portion on the lower side thereof. The light guide is formed such that an inner end of the stepped portion curves downward to reach the horizontal lower surface of the light guide, and a light source is housed in the notch of the light guide.
