Abstract
A backlight module includes a back board, a lamp board, a wavelength conversion film, an optical film, a coating layer and a reflective component. The back board includes a side wall. The lamp board is arranged on the back board, and includes plural light emitting units. The wavelength conversion film is arranged on the light emitting units. The optical film is arranged on the wavelength conversion film. The coating layer is arranged on the optical film, and adjacent to the optical film. The reflective component is arranged between the side wall and the optical film, and surrounds the wavelength conversion film and the optical film. At an optical wavelength of 450 nanometers, a brightness of a first surface of the reflective component is between 70 and 100, a first chromaticity thereof is between −10 and 10, and a second chromaticity thereof is between −10 and 10.
