Abstract
The display panel includes a planar display area and a curved display area. The display panel includes a light emitting layer, a cathode layer, and an optical coupling layer. A thickness of at least one of the cathode layer and the optical coupling layer in the curved display area is different from a thickness of at least one of the cathode layer and the optical coupling layer in the planar display area, so that a luminous efficiency of the light emitting layer in the curved display area is greater than a luminous efficiency of the light emitting layer in the planar display area. The brightness of the curved display area is improved, and the problem of low brightness of the display panel in the curved display area is improved.
