Abstract

Official abstract text for this publication.

A light guide plate having a V-cut structure and a backlight module are disclosed. The light guide plate comprises straight-striped V-cut structure sets and a base plate having a light-entering side. The straight-striped V-cut structure sets are formed on a surface of the base plate adjacent to the light-entering side, wherein each straight-striped V-cut structure set is composed of at least one V-cut element, each V-cut element having a first base angle and a second base angle formed between its respective two inclined surfaces and a horizontal surface of the base plate. The first base angle is located closer to the light-entering side than the second base angle is, and is smaller than or equal to the second base angle. The straight-striped V-cut structure sets have a plurality of second average angle values which are gradually decreased from the light-entering side to a central position of the base plate.
