The invention provides a curved surface display panel and a curved surface displayer. The curved surface display panel comprises an array substrate and a color film substrate which are arranged oppositely. A spacer is arranged between the array substrate and the color film substrate. The box thickness of the middle area of the curved surface display panel is unequal to that of the periphery area of the curved surface display panel, and therefore the light leakage amount generated when the periphery area is in a full dark state is different from that of the middle area. The curved surface displayer comprises the cured surface display panel provided by any embodiment of the invention. The curved surface display panel and the curved surface displayer can prevent brightness non-uniformity caused by curving of the curved surface display panel under the full black state of a screen.
