Abstract: A backlight module including a light source, a light guide plate, an optical film set and at least one optical film layer is provided. The light guide plate has a light-incident surface and a light-emitting surface adjacent to the light-incident surface. The light source is disposed on a side of the light-incident surface and emits a light beam. The optical film set includes a first surface, a second surface opposite to the first surface and at least one side surface connected between the first surface and the second surface. The optical film set is disposed on a side of the light-emitting surface of the light guide plate, and the first surface faces the light-emitting surface. The optical film layer is disposed on the side surface of the optical film set. The optical film layer is a particle structure layer. A display apparatus including the backlight module is also provided.

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.
