Abstract
A curved screen and a display device are disclosed. The curved screen includes a first substrate, a second substrate, and a liquid crystal layer disposed between the first and second substrates. The curved screen is bent and concave along the first substrate. The first substrate includes a substrate and a planarization layer disposed on a concave side of the substrate. A plurality of grooves are defined in the planarization layer and arranged at intervals along a direction of a bending edge of the curved screen, and extend in parallel along a direction of a non-bending edge. The depth of each groove before bending is greater than after bending.
