Abstract
The present invention provides a display device and a backlight module used therein. The backlight module includes a support frame, an optical plate, a load-bearing pin, and an optical film. The support frame encloses an accommodating space. The optical plate is disposed in the accommodating space and has a light-emitting surface and a first end. The load-bearing pin is connected to the support frame and disposed across the light-emitting surface in a position close to the first end. The optical film is disposed corresponding to the light-emitting surface and has a support end and a load-bearing end opposite to each other. The support end is supported by the support frame and the load-bearing end is connected to the first end. The load-bearing pin is located between the optical film and the optical plate and the optical film is held up by the load-bearing pin so that the direction of extension of the optical film is changed.
