The invention discloses a display, a manufacturing method thereof, and a preparation method of a photosensitive thin film. The display comprises a display screen for displaying a picture, and the photosensitive thin film attaching to the out-outgoing face of the display screen, wherein the photosensitive thin film can automatically adjust the corresponding transmittance according to the gray scale luminance of the picture displayed by the display screen, and the transmittance of the photosensitive thin film increases along with the increase of the gray scale luminance picture displayed by the display screen. Thus, by utilizing the photosensitive property of the photosensitive thin film, the luminance of the black area of the picture displayed can be reduced without influences on the display effect of the other display areas, namely, the visible light transmittance is reduced when the display displays the black picture, so that the black picture is darker, when the display displays other pictures, photoactive substances in the photosensitive thin film change so that the photosensitive thin film is transparent, and thus the transmittance is improved, and the normal display of the display is guaranteed; therefore, the contrast ratio of the display provided by the embodiment can be improved without changing the design of the existing display, and thus the display effect of the display is improved.
