摘要： A liquid crystal display device includes a liquid crystal panel and an illuminating device having a plurality of LED packages which include LED's and a lens. Each LED package includes a high refractive index member containing a substance having a larger refractive index than that of a material forming the lens and which seals the LED. The lens is shaped to have a recess near its center, and is shaped so that a moving radius increases as a polar angle increases within a range of 0 to 80 degrees. The moving radius is defined as a distance starting from the lens center and ending in the lens surface, and the polar angle is defined as an angle that is made by the moving radius to the center axis that is vertical to a plane on which said LED package is located and passing through the center of the lens.
