Abstract: A liquid crystal display panel is provided, and includes a color film substrate and an array substrate. The array substrate includes a device layer disposed on a glass substrate; and two ultraviolet protective layers disposed on the same side of the device layer. A first ultraviolet protective layer is close to the UV light source, and a second ultraviolet protective layer is far away from the UV light source. The refractive index of the first ultraviolet protective layer to UV light is greater than the refractive index of the second ultraviolet protective layer to UV light. One UV mask is reduced, to ensure that device characteristics remain unaffected.

Abstract: A polymer liquid crystal dimming box, a manufacturing method thereof, and a display module are provided. The polymer liquid crystal dimming box includes a first substrate, a second substrate, a polymer liquid crystal layer, a frame adhesive layer and a light-shielding structure. The light-shielding structure is disposed between the frame adhesive layer and the polymer liquid crystal layer and surrounds the polymer liquid crystal layer. The light-shielding structure is used to absorb ultraviolet light obliquely incident during the curing process of the frame adhesive layer. In this way, the problem that the polymer liquid crystal layer is cured in advance due to ultraviolet light irradiation can be avoided, the edge failure of the polymer liquid crystal dimming box can be improved, which is conducive to mass production.
