Abstract
A backlight module includes a frame, a first optical film and a fixing assembly. The frame has a near-display panel side and a far-display panel side in a direction perpendicular to a plane enclosed by the frame. The frame includes a frame portion and an extending portion disposed on an inside of the frame portion. The frame portion has at least one film fixing groove, a cross section of the film fixing groove has a stepped shape in a direction perpendicular to a plane enclosed by the frame portion and perpendicular to an edge of the frame portion where the film fixing groove is located. The film fixing groove has a first support surface and a second support surface, and the second support surface is farther away from the near-display panel side than the first support surface.
