The invention provides a backlight module made by quantum dots and a display device. The module comprises a glue frame, a light source assembly, a light guide plate, a quantum dot thin film, an intensifying film and a light-shielding adhesive tape. The quantum dot thin film, the intensifying film and the light-shielding adhesive tape are sequentially overlapped on the light guide plate in sequence. The glue frame surrounds the light guide plate, the quantum dot thin film, the intensifying film and the light-shielding adhesive tape and accommodates the light source assembly. The light-shielding adhesive tape comprises a black printing ink surface used for shielding light and a green printing ink surface used for shielding light opposite to the black printing ink surface. The green printing ink surface faces towards the quantum dot thin film and is used for reflecting green light and mixing with abnormal light emitted around by the quantum dot thin film. The backlight module made by quantum dots and the display device have following beneficial effects: the backlight module made by quantum dot enables the green quantum dots to lose efficiency due to the fact that light-shielding glue paper and the cuts around the quantum dot thin film are influenced by water and oxygen seepage such that abnormal coloured light is avoided, therefore emitting pure white light from edges of the quantum dot thin film. Therefore, display quality of the liquid crystal display panel is improved.
