Abstract
A liquid crystal display device includes a liquid crystal display panel and a backlight arranged on a back surface of the liquid crystal display panel, the backlight including a plurality of rod-shaped light sources, a frame which supports the rod-shaped light sources, and a heat radiation plate which is arranged on an inner surface of the frame. Through holes are formed in the frame, and heat radiation fins are formed on the heat radiation plate in a state that the heat radiation fins project toward a back surface of the liquid crystal display panel through the through holes formed in the frame. Due to such a constitution, it is possible to provide a liquid crystal display device which can enhance heat radiation efficiency.
