Abstract
A light-adjusting film is mounted between a color conversion layer and a display panel of a direct type backlight module and has a substrate and at least one light-adjusting layer. The substrate has a central area and a surrounding area. The at least one light-adjusting layer has a pigment and is mounted on the substrate. A content of the pigment is gradually decreased from the surrounding area to the central area. The color of the pigment of the light-adjusting film is a correction color of lights emitted from light emitting surface of the color conversion layer in the backlight module.
