Abstract
Disclosed is a liquid crystal display device containing an electrode substrate, a circuit substrate, and a flat-type back light, which incorporates a guide apparatus consisting of several guide members for guiding the back light onto the back surface of the electrode substrate, in which the guide members provide grooves with tapered ends and a narrowed shape at one end, but a wide juncture portion for connecting the guide members together. The edges of the back light unit fit in the grooves. Stopper members are provided facilitate connection to the electrode substrate; and fixing members are provided to secure the guide members to the circuit substrate.
