散光を照射するバツクライトにおいて、前記液晶
デイスプレイの背面側に位置し、光源が発した光
源光を拡散光とする拡散板と、この拡散板に光源
から直接入射しなかつた光源光を前記拡散板側に
反射する略樋形状のライトガイドと、前記光源と
拡散板との間に介在され、前記光源からの熱を液
晶デイスプレイに対して遮断する遮熱板とを具備
したことを特徴とするバツクライト。 In a back light that irradiates a transmissive liquid crystal display with uniform diffused light from the back, there is a diffuser plate located on the back side of the liquid crystal display that converts the light source light emitted by the light source into diffused light, and a diffuser plate that emits light from the light source directly to the diffuser plate. a generally gutter-shaped light guide that reflects the light source light that did not enter the diffuser plate; and a heat shield plate that is interposed between the light source and the diffuser plate and blocks heat from the light source from the liquid crystal display. Backlight is characterized by being equipped with.
