ABSTRACT:
A light guide plate includes two opposite incident surfaces for receiving light beams, an emitting surface joining the two incident surfaces and a bottom surface opposite to the emitting surface. The emitting surface has a V-shaped profile defined by two symmetric oblique surfaces slanting down toward each other at a predetermined angle. Further, each of the oblique surfaces defines a plurality of grooves extending therein and being arranged along an oblique direction thereof. The surface light source incorporating the light guide plate is inexpensive and has higher intensity of illumination at the center region thereof. Thus a liquid crystal display incorporating the surface light source satisfactorily illuminates a main visible range thereof.
