    Abstract: A stage circuit includes a first substage circuit unit connected to first through third input terminals receiving a start signal, a first clock signal, and a second clock signal, respectively. The first substage circuit unit generates first and second operation signals based on the start signal and the first and second clock signals, and supplies a first scan signal to a first output terminal based on the first and second operation signals. The stage circuit further includes a second substage circuit unit connected to the third input terminal and a fourth input terminal receiving a third clock signal. The second substage circuit unit supplies a second scan signal to a second output terminal based on the first and second operation signals, the second clock signal, and the third clock signal. The first and second scan signals include a pulse of a low voltage level and a high voltage level, respectively.

    Abstract: A display device includes a substrate which includes a display area and a non-display area, a pixel unit which is provided in the display area and includes a plurality of pixel columns, and data lines which are respectively connected to the pixel columns and apply data signals to the pixel columns. The non-display area includes a fanout area, a bent area, and a pad area which are sequentially arranged. The respective data lines are disposed on different layers in the fanout area and the pad area. A resulting display device can reduce resistance deviation between data signals in a first data line and a second data line, thereby reducing vertical line defects.

    Abstract: A display device includes a display panel including pixels in one pixel column and a gate driver for sequentially providing scan signals to the pixels. Each of the pixels includes a light emitting element, a first transistor for controlling a current amount of driving current flowing through the light emitting element and a second transistor for transferring a data signal to a gate electrode of the first transistor in response to a corresponding scan signal among the scan signals. A first pixel among the pixels is electrically connected to a first data line, and a second pixel adjacent to the first pixel among the pixels is electrically connected to a second data line different from the first data line. A second scan signal provided to the second pixel partially overlaps with a first scan signal provided to the first pixel.
