Abstract: Provided is a display panel including a base layer in which an emission area and a peripheral area adjacent to the emission area are defined, an insulation layer disposed on the base layer and in which a groove overlapping the emission area is defined, a pixel defining film disposed on the insulation layer and in which an emission opening portion overlapping the groove is defined, a partition wall disposed on the pixel defining film and in which a partition wall opening portion overlapping the emission opening portion is defined, and a light emitting element disposed in the partition wall opening portion, the light emitting element including an anode, an intermediate layer, and a cathode that is in contact with the partition wall. The insulation layer includes an inner side surface defining the groove and is inclined at a first angle with respect to a top surface of the base layer.
