SURFACE ILLUMINATION DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE USING SAME

摘要

A surface illumination device comprises optical waveguides which scanning beams of different scan sections in a scan area of a scanning unit enter respectively and an illumination unit including light-emitting regions for emitting beams guided by the-optical waveguides respectively. The number of the light-emitting regions is equal to or more than two and equal to or less than 1000, and the light-emitting regions are structured to emit light in sequence when the scanning beams enter the respective optical waveguides.
