Abstract

The present invention provides a liquid crystal display device having a linear light source, which is easily treated, in consideration of the heat radiation of a light-emitting diode in the liquid crystal display using the light-emitting diode as a light source. A light-emitting diodeis provided on a metal substrate. The metal substrateis formed in a case shape such that the heat generated at the light-emitting diodereceived in the case is efficiently radiated. A resin materialis filled in the metal case to form a plate-shaped light source. It is possible to improve reliability during the handling in the manufacturing process by filling the resin materialto form the plate-shaped light source. It is possible to improve heat radiation effect by filling the resin material
