A curved display panel includes an array substrate, an opposite substrate and a plurality of overhanging spacers which are disposed between the array substrate and the opposite substrate and located in non-display regions of the display panel. A height of the overhanging spacer is less than a spacing between the array substrate and the opposite substrate. Between the array substrate and the opposite substrate, a sealing agent structure is placed against at least one overhanging spacer in the non-display region where a side edge adjacent to a curved side edge of the array substrate or the opposite substrate is located. The sealing agent structure contacts with the overhanging spacer against which said sealing agent structure is placed, and a sum of a thickness of the overhanging spacer and a thickness of the sealing agent structure contacting with said overhanging spacer is equal to the spacing.
