Abstract: A display panel includes a transistor, a first insulation layer disposed on the transistor, a pixel definition layer disposed on the first insulation layer and having a light emitting opening and an opening pattern surrounding the light emitting opening, a light emitting element disposed on the first insulation layer and including a first electrode at least a portion of which is exposed by the light emitting opening and a second electrode which is electrically connected to the transistor, and a connection line disposed on the transistor and electrically connecting the transistor and the second electrode. A groove overlapping the opening pattern is defined in the first insulation layer, and a portion of the pixel definition layer protrudes from an edge of the first insulation layer defining the groove toward an inside of the opening pattern.

Abstract: A display panel includes a display area and a peripheral area adjacent to the display area and includes a transistor, a light emitting device including a first electrode and a second electrode disposed on the first electrode and electrically connected to the transistor, a separator, a power line at least partially disposed in the peripheral area, and a separation conductive layer including a first portion disposed on the separator and a second portion disposed in the peripheral area. An outer side surface of the separator includes a connection area, and an interior angle between the connection area and a lower surface of the separator is smaller than an interior angle between an inner side surface of the separator and the lower surface of the separator.
