Abstract
A subject of the present invention is to provide a liquid crystal display device in which the reliability of electrical connection between electrodes and electrode fittings can be improved even if there are variations in diameter of the bar light sources arranged in the back light. There is provided a liquid crystal display device comprising: a liquid crystal display panel; and a back light arranged on the back surface of the present liquid crystal display panel; wherein the back light is composed of a plurality of bar light sources arranged in parallel in a plane opposing the liquid crystal display panel and a base that supports each of the bar light sources through electrode fittings at electrode sections; wherein the electrode fittings are each provided with a pair of pressing portions which press the circumferential surface of the electrode of the bar light source from opposing sides of the circumferential surface; and wherein each of the pressing portions is arc-shaped such that the pressing portion surface facing the circumferential surface of the electrode of the bar light source has a concave; and is formed such that the pressing portion presses the electrode of the bar light source through projections formed on the concave.
