Abstract: Disclosed is a display panel, including a liquid crystal cell and a polarizing assembly disposed on the liquid crystal cell. The liquid crystal cell includes a display area, a transparent homogeneous dielectric layer is disposed between the polarizing assembly and the display area. The polarizing assembly includes: a substrate, a first polarizer and second polarizers. The first polarizer includes a first alignment layer and a polarizing layer, the first alignment layer is disposed on the substrate, and the polarizing layer is disposed on a side of the first alignment layer facing away from the substrate. The second polarizers are disposed on the substrate, and two adjacent second polarizers are disposed on opposite sides of the first alignment layer.

Abstract: The present application relates to a display panel. By adjusting a width of a second branch electrode connected to a second trunk electrode parallel to an axis of curvature of the display panel, a width of an end of the second branch electrode close to the second trunk electrode is smaller than a width of an end of the second branch electrode away from the second trunk electrode.
