Abstract
A backlight module includes the following features. A light guide plate has a viewing angle convergence structure, a light-incident surface and a surface connected to the light-incident surface. The viewing angle convergence structure is located at the surface. The prism plate has first prism columns and second prism columns disposed cross to each other. The inverse prism plate has third prism columns respectively having a first side surface and a second side surface. The first side surface and the second side surface are connected to each other and are respectively connected to the second surface. The first side surface faces a side of the backlight module with the light-emitting element, and the second side surface faces away from the side. An included angle between the first side surface and the second surface is larger than an included angle between the second side surface and the second surface.
