Abstract: The present disclosure discloses a backlight module and a display device. The light emission direction of at least one of the lamp source and the fluorescent film is provided with a diffusely reflecting layer. The diffusely reflecting layer arranged above the lamp source diffusely reflects pump light emitted from the lamp source, which may enhance uniformity of the pump light. The diffusely reflecting layer arranged above the fluorescent film scatters light emitted from the fluorescent film, scatters the light and distributes the light to a larger range, which may improve light mixing uniformity and improve the uniformity of light emission brightness.

Abstract: The present disclosure provides a liquid crystal display and a display module thereof, the display module includes a lower polarizer, a TFT array substrate, a liquid crystal layer, a color filter and a upper polarizer. The display module further includes a metal electrode layer arranged between the color filter and the liquid crystal layer, the metal electrode layer includes a dielectric layer and a metal wire grid layer, and the metal wire grid layer is arranged on a surface of the dielectric layer facing the liquid crystal layer. The metal wire grid layer is used as a common electrode layer of the display module, thus replacing the traditional transparent electrode ITO and avoiding the problem that the transparent electrode ITO easily causes brittle fracture during bending resulting in electrical abnormality and at the same time can improve the contrast of the entire liquid crystal display.
