Abstract: Provided is an organic light-emitting display device which enables a fast and secure repair process without changing optical characteristics. The organic light-emitting display device includes a lower electrode, an organic emitting layer, an upper electrode and an optical compensation layer which are sequentially stacked. The upper electrode is thinner than the lower electrode. An opening is formed by particles in the organic emitting layer and the upper electrode. The opening caused by the particles is extended between the lower electrode and the organic emitting layer.

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.

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.
