PURPOSE: A light guide plate, a back light, and a plurality of light guide plates are provided to lower the thickness of the back light by forming the back light connecting a plurality of small light guide plates. CONSTITUTION: A light guide plate comprises a light guide plate body(1), an assembly part(3), and a patterned part(7) for diffusion. The light guide plate body has a space for installing a light source. The assembly part is connected to a plurality of different light guide plates. The assembly part is formed on the left and right sides of the light guide plate body. A reflective patterned part(5) includes light scattering or reflective pattern which are formed by processing the lower part of the light guide plate body. The patterned part for diffusion is formed into light scattering/diffusion/light concentration pattern by processing the upper side of the light guide plate body. The light reflected from the reflective patterned part is outputted to a diffuse sheet. |
