Abstract

A backlight module and a display. The backlight module comprises a light guide plate (10), a light source assembly (20), a frame (30) and multiple layers of optical films (40). The frame (30) surrounds the light guide plate (10). The light source assembly (20) is arranged between one edge of the light guide plate (10) and the frame (30). The light source assembly (20) comprises a circuit board (22) and a light-emitting piece (24). The light-emitting piece (24) is located between the light guide plate (10) and the frame (30). The circuit board (22) is located above the edge of the light guide plate (10). The optical films (40) are stacked on the light guide plate (10). The backlight module further comprises a first double-faced adhesive tape (50) and a second double-faced adhesive tape (60). The edges of the optical films (40) are stacked and arranged in a step-like manner.
