Abstract
A backlight module includes a back plate, an optical element set, a wavelength conversion film, a light source, and an ink layer. The optical element set is disposed on the back plate and has a first surface, a second surface and at least one end surface. The first surface faces the back plate and is opposite to the second surface. The at least one end surface is connected to the first surface and the second surface. The wavelength conversion film is disposed on the back plate. The light source is adapted to provide light, and the light is transmitted to the wavelength conversion film and the optical element set. The ink layer is disposed on the at least one end surface of the optical element set. A display device is further provided. The backlight module and the display device may reduce the phenomenon of blue edge caused by light leakage.
