Abstract: A display device and a backlight module thereof are provided. The backlight module includes a collimated light source and a light guide plate. The collimated light source configured to generate a collimated light. The light guide plate has a bottom surface and a top surface opposite to each other, and a light entrance surface connected to ends of the bottom and top surfaces respectively for receiving collimated light from the collimated light source. The bottom surface inclines toward the top surface from the end of the bottom surface connected to the light entrance surface. A plurality of first grooves are disposed side by side on the bottom surface and respectively extend along the light entrance surface. The first groove has a first light receiving surface with a first end extending toward the top surface and inclining away from the light entrance surface. Compared to the first end of the first light receiving surface closer to the light entrance surface, the first end of the first light receiving surface farther from the light entrance surface has a vertical projection position on the light entrance surface that is closer to the top surface.
