The present invention provides a liquid crystal display device which can enhance the reliability of electrical connection between electrodes and metal fittings even when the irregularities exist with respect to radii of rod-shaped light sources arranged in the inside of a backlight. 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, wherein the backlight includes a plurality of rod-shaped light sources each having electrode portions at both ends thereof and a base which supports the respective rod-shaped light sources at the respective electrode portions by way of an electrode fitting, the electrode fitting is configured to fix the rod-shaped light source by clamping the electrode portion, the electrode fitting being formed of a plurality of electrode fittings arranged in parallel in the longitudinal direction of the rod-shaped light source for every electrode, and each electrode fitting has an arcuate wall surface, and the respective electrode fittings arranged in parallel in the same electrode portion have radii of arcs of the wall surfaces thereof made different from each other.
