Light emitted in side surface directions from side-emitting red, green, and blue LEDs which are arranged on an LED array substrate is introduced into a light guide from side surfaces of a groove-shaped recessed portion, and propagates in the light guide. Thus, the three colors are mixed. The light further propagates in the light guide while being reflected at both side end surfaces of the light guide by the function of a reflective sheet and the like. Thus, color mixing progresses. Further, the light is reflected upward by diffuse reflective means provided on the lower surface of the light guide, and emitted as backlight light to the outside through a diffuse sheet.
