A display panel including: a display region including pixels and a non-display region, each pixel including an emission element including a first electrode, an emission layer, and a second electrode; a pixel definition layer including a first opening; a first encapsulation layer on the pixel definition layer and overlapping the emission element; a partition wall on the first encapsulation layer and including a second opening and a dummy opening; a light control pattern in the second opening; a second encapsulation layer on the partition wall and overlapping the light control pattern; and a color filter on the second encapsulation layer and overlapping the light control pattern, the second encapsulation layer includes: a first encapsulation inorganic layer on the partition wall; an encapsulation organic layer on the first encapsulation inorganic layer and including an edge overlapping the dummy opening; and a second encapsulation inorganic layer on the encapsulation organic layer.

Display panel

A display substrate includes a base substrate and a plurality of insulating layers disposed on a surface of the base substrate. A groove is defined in the insulating layers in a non-display area of the display substrate. An end portion of an alignment layer is disposed in the groove. The groove is capable of controlling a flow of a liquid alignment material to prevent the liquid alignment material from overflowing to an edge of the base substrate. The groove is formed simultaneously in a process of forming contact holes in a display area of the display substrate. Accordingly, a structure corresponding to the end portion of the alignment layer to control the flow of the liquid alignment material is formed without increasing the number of masks.
