Display panel

A display panel comprising:

• a base layer comprising a first pixel region, (2-1)-th and (2-2)-th pixel regions at least partially spaced apart from each other in a first direction with the first pixel region interposed between the (2-1)-th and (2-2)-th pixel regions, and a non-pixel region adjacent to the first pixel region and the (2-1)-th and (2-2)-th pixel regions;
• a pixel defining layer disposed on the base layer and having a first pixel opening defined in the pixel defining layer and corresponding to the first pixel region and (2-1)-th and (2-2)-th pixel openings defined in the pixel defining layer and respectively corresponding to the (2-1)-th and (2-2)-th pixel regions;
• and
• a light-emitting portion overlapping the first pixel region and the (2-1)-th and (2-2)-th pixel regions, disposed on the pixel defining layer, and comprising a charge generation layer,
• wherein the pixel defining layer comprises:
• at least one first valley region and at least one first non-valley region disposed on a first virtual line completely enclosing the first pixel opening;
• at least one first group valley region and at least one first group non-valley region disposed on a (2-1)-th virtual line completely enclosing the (2-1)-th pixel opening;
• and
• at least one second group valley region and at least one second group non-valley region disposed on a (2-2)-th virtual line completely enclosing the (2-2)-th pixel opening,
• wherein:
• the at least one first group non-valley region and the at least one second group non-valley region are not disposed on a same line in the first direction;
• and
• on a plane, the at least one first valley region is asymmetric with respect to a reference line passing through a center of the first pixel region and extending in a second direction perpendicular to the first direction.
