Abstract
The present invention includes a liquid crystal panel, a light guide member, at least one laser diode (LD), and a heat sink. The light guide member is arranged on a back surface of the liquid crystal panel. The LD is arranged on at least one side surface of the light guide member. The heat sink is arranged to extend along a back surface of the light guide member and the side surface of the light guide member integrally and at least partially. The heat sink is arranged such that a part of the heat sink corresponding to the side surface of the light guide member houses at least a light-emitting surface of the LD.
