Occurrence of an event can be prevented, whereby, when a backlight expands with heat, a light guide plate might move a group of optical sheets into contact with a middle frame and deform the sheets, thereby causing nonuniformity of luminance on a screen. In particular, a protrusion is formed at an edge of the plate, and the sheets are mounted on the plate to avoid the protrusion. The frame covers the protrusion and the edge of the sheets. Even if a spatial gap with respect to the frame is lost by expansion of the plate, the sheets suffer no deformation due to interference between an edge of the sheets and the frame. Therefore, the nonuniformity of luminance on the screen does not occur, either. Also, unusual sounds due to movement of the plate under vibration do not arise since a gap between the protrusion and the frame can be small.
