Abstract

A display panel includes a base, at least one separation pillar, at least one protection pattern, and a light-emitting functional layer. The at least one separation pillar is disposed in the isolation region on the base, each separation pillar is disposed around the opening region, and a longitudinal section of the separation pillar perpendicular to an extending direction of the separation pillar is I-shaped. The at least one protection pattern is disposed on a surface of at least one separation pillar facing away from the base. The light-emitting functional layer is disposed at least in both the pixel region and the isolation region on a surface of the at least one protection pattern facing away from the base, wherein the light-emitting functional layer is disconnected at an inner side face and an outer side face of the separation pillar.
