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.

Abstract: A display device includes the following elements: a light emitting diode; a first transistor including a drain electrode, a source electrode, and a gate electrode, the drain electrode being connected to the light emitting diode; a second transistor connected between a data line and the source electrode; a third transistor connected between the drain electrode and the gate electrode; and a fourth transistor connected between a first initialization voltage source and the gate electrode. The third transistor is off for a first period, on for a second period immediately following the first period, and off for a third period immediately following the second period. The fourth transistor is off for a fourth period, on for a fifth period immediately following the fourth period, and off for a sixth period immediately following the fifth period. The second period overlaps the fifth period.

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.
