Abstract

A backlight module includes the following features. A privacy film is disposed on a light path of a light source assembly. A light guide plate has optical microstructures, a light incident surface and a surface connected to each other. The surface faces the privacy film. The optical microstructures each have a rounded corner, and a first convex surface and a second convex surface that stand on the surface. The rounded corner is connected to the first convex surface and the second convex surface. An angle between the first convex surface and the surface is 30°-70°, and the radius of curvature of the rounded corner is 0.001-0.005 mm. The first convex surface faces the light incident surface when the optical microstructures are sunken from the surface. The first convex surface faces away from the light incident surface when the optical microstructures are protruded from the surface.
