Abstract

The invention discloses a light guide plate with high luminous efficiency and uniform brightness and a manufacturing method thereof. The light guide plate comprises a body, the upper surface of the body is provided with light guide grids, and the density of the light guide grids increases gradually from one end to the other end of the body. According to the light guide plate with high luminous efficiency and uniform brightness and the manufacturing method thereof, the light guide grids carved on the body can diffuse light emitted by a light source; the intersections of the light guide grids are provided with light guide grooves, so light can be diffused better; and as the density of the light guide grids increases gradually from one end to the other end of the body, light can be diffused more uniformly.
