Title: BACKLIGHT MODULE AND DISPLAY DEVICE
Abstract:
A backlight module and display device. The backlight module comprises a light guide plate (30) and an optical film group (40) vertically stacked and multiple stopper blocks (1), and the periphery of the light guide plate (30) is projectedly provided with the same number of engagement portions (31) as the stopper blocks (1). The stopper blocks (1) are fixed to a back portion of the optical film group (40) and engaged with the engagement portions (31). By disposing the multiple stopper blocks (1) at the periphery of the backlight module and the engagement portions (31) cooperating therewith, and using the stopper blocks (1) to stop the light guide plate (30) and the optical film group (40), the present invention reduces the space occupied by positioning mechanisms of a reflector (20), the light guide plate (30) and the optical film group (40), thereby facilitating an ultra-slim frame design of a display device, and improving the product assembly efficiency.
