ABSTRACT:
A light source includes a plurality of light emitting elements, and each light emitting element is disposed in such a manner that a direction of an optical axis of the light emitting element having a highest luminance is disposed at a predetermined inclination angle relative to a plane of the liquid crystal display. The optical guide member has an optical guide portion of a wedge shape having a first flat plane generally perpendicular to the optical axis of each light emitting element for receiving light from each light emitting element and a second flat plane having a predetermined angle relative to the optical axis and intersecting the first flat plane at an acute angle for reflecting light. A plurality of optical guide portions are disposed in a plane and formed integrally along a predetermined direction corresponding to the inclination direction of the light emitting elements.
