Abstract

The present application provides a display device. The display device comprises a quantum dot composite film, a liquid crystal display panel and a backlight module. The quantum dot composite film comprises a quantum dot film layer, and a light emerging surface of the quantum dot film layer is provided with a plurality of first prism structures. The first prism structure is employed to reduce an angle at which light emerges from the quantum dot film layer, thereby improving the front view brightness of the display device, and improving or avoiding the problem of light leakage of the display device in the large viewing angle of the dark state.
