By above-described embodiment it is found that curved face display panel provided by the invention and curved-surface display device, at least realize
Following advantageous effect：
Curved face display panel is divided into central area and corner region by the present invention according to the stressing conditions of different zones, and in center
The spacer of area and corner region setting different densities different height is subject to when curved face display panel is bent due to central area
Stress is maximum, therefore is all higher than corner region in the spacer density of central area setting and height, to increase the resistance to compression of central area
Ability reduces the box thickness variable quantity caused by bending of curved face display panel 100.In addition, the set-up mode of spacer is from center
To corner region B density and/or highly, successively gradual change type reduces in area, that is to say, that and spacer changes in a plurality of directions,
It is capable of the box thickness of profile of equilibrium display panel due to being bent the inconsistent of appearance, improves curved face display panel and shown not in corner region
Equal phenomenon so that the box thickness of central area C and corner region B reaches unanimity, and improves the display quality of curved face display panel 100.
