Abstract: A display panel having an improved opening ratio and a manufacturing method of the display panel are discussed. In the display panel, a storage capacitor includes a bottom electrode, a buffer layer disposed on the bottom electrode, a middle electrode covering a portion of the buffer layer, a gate insulating layer covering the middle electrode and the buffer layer, and an upper electrode covering a portion of the gate insulating layer. In the buffer layer, a thickness of a first area covering the middle electrode is greater than a thickness of a second area that is in contact with the gate insulating layer.

Abstract: Provided is an organic light-emitting diode (OLED) display device. The OLED display device includes a substrate in which a pixel area and a non-pixel area are defined, a power line formed on the substrate, at least one insulating film covering the power line, a light-emitting element formed on the insulating film, a connection electrode connected to the power line and formed to extend along an upper surface of the insulating film, and a passivation film having a contact hole through which a portion of the connection electrode is exposed within the non-pixel area. The light-emitting element includes a first electrode, an emissive layer, and a second electrode that are sequentially stacked. The second electrode is in direct contact with the connection electrode within the contact hole.
