<p>Disclosed is a liquid crystal display device which can achieve low cost, while eliminating moving image blurring. The liquid crystal display device is provided with a liquid crystal panel and a backlight device. The backlight device has a light guide plate (10) having a rectangular shape in planar view, and a light source section which outputs light toward the light input plane that corresponds to the side planes of the light guide plate, and the light source section is configured of a plurality of light source blocks disposed in the Y direction. The light guide plate (10) is provided with a groove structure (32) for extracting light upward, said groove structure being formed on the front surface that faces the back surface of the liquid crystal panel, and dot patterns (31) for scattering light, said dot patterns being formed on the rear surface. In the groove structure (32), groove sections extending in the X direction are formed in a plurality of stripe shapes, and ridge portions extending in the X direction are formed on the portions sandwiched by the adjacent two groove sections.</p> |
