Abstract
According to one embodiment, a liquid crystal display device includes a liquid crystal cell, light source devices and a light guide plate. The light guide plate applies, to a rear surface of the liquid crystal cell, light beams from the light source devices. The light guide plate includes a first light input portion at a first-shorter-side side surface and a second light input portion at a second-shorter-side side surface. The light guide plate includes a flat first surface opposed to the rear surface and a second surface opposite to the first surface. The second surface includes a first slant surface inclined so that a thickness of the light guide plate decreases as a position goes from the first-shorter-side side surface to an approximately central portion and a second slant surface inclined so that the thickness decreases as a position goes from the second-shorter-side side surface to the approximately central portion.
