Claim 0:
1. An organic light-emitting panel having an active area and a non-active area located at a periphery of the active area, the organic light-emitting panel comprising:
a substrate;
a planarization layer disposed on the substrate, the planarization layer including a first side surface having a first inclination angle and a second side surface having a second inclination angle that is different from the first inclination angle, each of the first and second side surfaces extending from a top surface of the planarization layer to a bottom region of the planarization layer;
a contact hole in the planarization layer and located in the active area, the contact hole being adjacent to the second side surface of the planarization layer, the second side surface of the planarization layer being a side surface of the contact hole;
a first electrode disposed on the planarization layer;
a bank disposed on a portion of a top surface of the planarization layer and a portion of a top surface of the first electrode;
an organic layer disposed on the top surface of the first electrode disposed in a first open area of the bank in the active area;
a second electrode disposed on the organic layer and the bank;
a dam located in the non-active area to at least partially surround the active area;
an encapsulation member disposed on the second electrode and the substrate on which the dam is disposed; and
a connector electrode disposed on the planarization layer in the non-active area, and electrically connected to the second electrode,
wherein, from among side surfaces of the planarization layer, the first inclination angle of the first side surface of the planarization layer is located in the non-active area and closest to the dam and the second side surface is located in the active area,
wherein the first inclination angle of the first side surface with respect to a top surface of the substrate is smaller than the second inclination angle of the second side surface of the planarization layer, with respect to the top surface of the substrate, and
wherein the first side surface of the planarization layer extends from an outermost portion of a top surface of the planarization layer to an end portion of the planarization layer in the non-active area.
