Abstract: The present invention provides a display device, including a display panel provided with an electromagnetic induction layer and a backlight module provided with a quantum dot film The quantum dot film contains a plurality of second-color quantum dots, a plurality of third-color quantum dots, and a plurality of magnetic particles. The electromagnetic induction layer is configured to generate a directional magnetic field to make the magnetic particles move directionally in the quantum dot film, and to make a density of the second-color quantum dots and the third-color quantum dots located in an edge area of the quantum dot film greater than a density of the second-color quantum dots and the third-color quantum dots located in a central area of the quantum dot film.
