Abstract: The present application provides a prism sheet and a display module. The prism sheet includes a base layer and a plurality of prisms arranged on the base layer. The prism sheet is divided into a middle region and edge regions. By making the vertex angles of the portions of the prisms in the middle region smaller than the vertex angles in the edge regions, it may be possible to improve the brightness of the backlight module in the display module and optimize the horizontal viewing angle of the display module.
