摘要： The present invention provides a backlight and a display device. The backlight includes a frame and an optical film set including a plurality of optical films that are successively stacked. Each optical film in the optical film set includes a film body and an ear part. In any two adjacent optical films, the boundary of at least one side of the ear part of the lower optical film extends beyond the boundary of the same side of the ear part of the upper optical film. A fixing member covers the ear parts of the plurality of optical films, such that the optical film set is fixed on the frame, and the fixing member can fix the relative positions among the plurality of optical films in the optical film set. In the backlight, the optical film set is reliably fixed without affecting the normal display on the display device.
