Abstract
A lighting device includes first light sources of a first row having first light emission surfaces and second light sources of a second row having second light emission surfaces, a first light guide plate including a first light entering edge surface that is opposite the first light emission surfaces, a second light guide plate including a second light entering edge surface that is opposite the second light emission surfaces, and a vertical dimension of the first light emission surfaces is greater than a thickness dimension of the first and second light guide plates and the vertical dimension of the second light emission surface is equal to or greater than the thickness dimension. The first light sources and the second light sources are arranged alternately in an extending direction of the light entering edges and portions of the first light emission surfaces are opposite the second light entering edge surface.
