Abstract

The present invention relates to a light guide plate and a backlight module using the same. The light guide plate includes a light incident surface, a light emission surface perpendicular to the light incident surface, and a bottom surface opposite to the light emission surface. The light guide plate is bi-refringent, and has stress therein. An angle between the direction of one of the main stresses and the light incident surface is larger than 0 DEG and smaller than 90 DEG. The light emission surface can further includes sub-wavelength grating.
