Abstract
A display device includes a backlight module, a display panel, and a prism film. The backlight module has a light-emitting surface and generates backlight along an average light-emitting direction that is inclined with respect to the light-emitting surface. The display panel is disposed above the light-emitting surface such that backlight from the backlight module passes through the display panel along the inclined direction. The prism film is disposed on one side of the display panel opposite to the backlight module, wherein the prism film has a plurality of prisms disposed side-by-side on one side of the prism film facing the display panel. An extending direction of the prisms at least partially traverses across the average light-emitting direction. Two sides of each prism are respectively a first surface and a second surface, wherein the first surface and the second surface are asymmetric and projection areas of the first surface and the second surface onto the prism film do not overlap. An angle between the first surface and a normal line to the light-emitting surface is greater than an angle between the second surface and the normal line to the light-emitting surface.
