The invention provides a curved surface display capable of reducing light leakage. The curved surface display comprises a liquid crystal panel, a glue frame, protecting glass, a front frame and a diffusion plate. The liquid crystal panel comprises a visible area and a peripheral area, the peripheral area comprises a black matrix layer, the glue frame comprises a first step portion and a second step portion, one end of the protecting glass is placed on the first step portion while the lower surface of the same is fitted to the liquid crystal panel, a first lateral side of the front frame is fitted with the glue frame while a second lateral side of the same is fitted to one part of the upper surface of the protecting glass, the diffusion plate is disposed on the second step portion, and the upper surface of the diffusion plate emits light to the liquid crystal panel. The second step portion is provided with a retaining wall, the diffusion plate is provided with a groove, and the light is blocked from penetrating to the edge of the liquid crystal panel by the retaining wall inserted into the groove. Compared with the prior art, the curved surface display has the advantages that the retaining wall is arranged on the second step portion of the glue frame, the groove is formed in the diffusion plate, and after the retaining plate is inserted into the groove, the retaining wall can be utilized to block the light to penetrate to the edge of the liquid crystal pane, so that the problem of light leakage of existing curved surface displays can be solved, and the diffusion plate can be reinforced and fixed.
