The invention discloses a quantum dot display. The quantum dot display comprises an upper polaroid, a display panel, a lower polaroid and a quantum dot film which are arranged in the direction back tothe light emitting direction; a light absorption axis of the upper polaroid forms a first angle with the vertical polarized light in incident light so as to absorb the vertical polarized light; and the light absorption axis of the lower polaroid forms a second angle with the vertical polarized light in the incident light so as to absorb the horizontal polarized light. The quantum dot display disclosed by the invention controls the polaroids to absorb the polarized light without a diffusion effect by adjusting the microstructures of the polaroids, and finally achieves the effect of diffusing blue light through the polarized light with the diffusion effect. The quantum dot display disclosed by the invention can effectively improve the viewing angle of the blue light, improve the general problem of large viewing ang
