Abstract
A display device includes a display panel and a backlight module. The backlight module is arranged under the display panel. The backlight module includes a matrix of light sources and a reflective sheet. The reflective sheet is disposed around or on at least one corner of the matrix of light sources. The reflective sheet has an upper edge, a reflective surface and a lower edge. The upper edge is far away from the matrix of light sources relative to the lower edge. A light conversion coating having a plurality of dots of different sizes is formed on the reflective surface. The matrix of light sources emits a first light toward the reflective sheet, and the first light is changed by the light conversion coating to form a second light, wherein the first light and the second light are of different colors.
