Abstract
The disclosure is related to a light guide plate having a light-emitting surface, wherein a plurality of V-shaped grooves is formed on the light-emitting surface; each of the V-shaped grooves extends along a curved path. The V-shaped grooves of the light guide plate extend along the curved path to avoid the light guide plate from collecting light in a single direction. The interference fringes of the light guide plate are reduced, thereby improving the uniformity of light emission of the light guide plate.
