Abstract: A method of manufacturing a display apparatus includes forming a first conductive layer on a base substrate including a panel area and a margin area disposed next to the panel area, the margin area including a dummy pattern area, forming a photoresist layer on the first conductive layer, forming a photoresist pattern by exposing and developing the photoresist layer, forming a first conductive pattern by etching the first conductive layer using the photoresist pattern, and removing the photoresist pattern. The forming the first conductive pattern includes forming a first pixel circuit pattern in the panel area, and forming a dummy pattern in the dummy pattern area of the margin area. An opening ratio of a portion where the dummy pattern is not formed with respect to the dummy pattern area is about 30% or more.

Abstract: An organic light emitting diode display device includes a substrate, a pixel structure, a lower blocking member, an upper blocking member, and a metal member. The substrate includes a display area and a peripheral area. The pixel structure is in the display area on the substrate. The lower blocking member is in the peripheral area on the substrate and surrounds the pixel structure, and includes a first side surface adjacent to the pixel structure, a second side surface, and a top surface. The upper blocking member is on the top surface and the second side surface of the lower blocking member, and constitutes a first blocking structure with the lower blocking member. The metal member is between the first blocking structure and the substrate while making contact with a bottom surface of the upper blocking member on the second side surface of the lower blocking member.

Abstract: A display device includes an insulating layer disposed on a substrate, a pixel electrode including a first conductive layer, a second conductive layer, and a third conductive layer sequentially stacked on the insulating layer, a pixel defining layer covering the pixel electrode and partially exposing the pixel electrode through an opening, an organic light emitting layer disposed in the opening of the pixel defining layer, and an opposing electrode disposed on the organic light emitting layer and overlapping the pixel electrode. A length of the first conductive layer is less than a length of the second conductive layer.
