Abstract

The present disclosure relates to a display panel, a display screen, and a terminal device. The display panel includes a substrate, a first pixel electrode overlaying the substrate, a pixel definition layer overlaying a side of the first pixel electrode away from the substrate and including a plurality of pixel openings to expose a surface of the first pixel electrode, and a first type of separation pillar disposed on the pixel definition layer. A width of the first type of separation pillar changes continuously or intermittently in an extending direction thereof. The extending direction of the first type of separation pillar is parallel to the substrate. The width is a dimension of a projection of the first type of separation pillar on the substrate in a direction perpendicular to the extending direction of the first type of separation pillar.
