Abstract
A curved display panel and a curved display device are disclosed. The curved display panel includes a first substrate, a second substrate disposed opposite to the first substrate, and a plurality of spacers disposed between the first substrate and the second substrate. The plurality of spacers is configured to define a space between the first substrate and the second substrate. The first substrate includes a display area, a frame area, and an array arrangement disposed in the display area. The array arrangement includes a plurality of active switches and a plurality of pixel cells. In a planar state, each spacer is away from a corresponding active switch by a deviation distance; and in a curved state, a position of each spacer overlaps that of the corresponding active switch.
