ABSTRACT:
A surface light source device. A light guide plate has an incident end face, an emitting face, at least one full-reflective face, and a plurality of light adjusters. The full-reflective face reflects light onto the incident end face for direction to the emitting face for transmission. The light adjusters are disposed in the light guide plate with a density discontinuously varied in at least one area of the light guide plate to adjust light collection for emission from the different areas of the emitting face, hereby providing discontinuous light intensity. The light source is disposed in the vicinity of the incident end face.
