Abstract: An organic light-emitting display device is discussed, which reduces the area of a pixel drive circuit and increases the aperture ratio of a pixel by forming lines inside the pixel using a semiconductor pattern that forms a channel of each thin-film transistor array. The light-emitting display device includes a plurality of pixels arranged in a matrix form and a plurality of lines configured to supply a signal for driving each pixel, each pixel includes a thin-film transistor including an active layer having a first area and a second area, which are configured as conductors, and a gate electrode, and at least one of the first area and the second area is directly connected to a corresponding line among the lines.

Abstract: Disclosed are a display device for preventing loss of line patterns and a method of manufacturing the display device. The display device includes a substrate having an active area, a non-active area, and a pad portion formed at one side of the non-active area, printed circuit films disposed in the pad portion so as to be spaced a first distance apart from an edge of the substrate in a first direction and to be spaced apart from each other in a second direction that intersects the first direction, a first-layer line and a second-layer line disposed within the first distance between the printed circuit films and the edge of the substrate so as to be spaced apart from each other in the first direction, and island-shaped dummy patterns disposed in the same layer as the second-layer line in a region between two adjacent ones of the printed circuit films.

Abstract: An organic light-emitting display device comprises a substrate, a driving thin-film transistor including an active layer on the substrate, source and drain electrodes directly contacting the active layer, and a gate electrode on the active layer, and an organic light-emitting element connected to the driving thin-film transistor. Each of the source and drain electrodes of the driving thin-film transistor exposes a respective side surface of the active layer.
