Abstract: A display apparatus, including: a backlight module and a panel. The backlight module includes: a circuit board, a light-emitting device, and a quantum dot film layer; a fluorescent layer is provided in an orthographic projection area of the light-emitting device on the circuit board, and the fluorescent layer can absorb incident light and excite white light. When light emitted from the light-emitting device is incident onto the orthographic projection area, the fluorescent layer may first excite white light using a portion of the light, so that the intensity of light reflected to the quantum dot film layer is relatively weakened to just meet requirements of a quantum dot material on saturation of excited light, and the excited light of the quantum dot material and unexcited blue light may be mixed into white light which provides white backlight for the panel together with the white light excited by the fluorescent layer.
