    摘要: A display device includes a scan driver supplying a scan signal to scan lines (Si, Si-1), an emission control driver supplying an emission control signal to emission control lines (Ei), and a data driver supplying data signals to data lines (Dm) coupled to pixels (142). Each pixel (140) includes a drive transistor (MD) controlling an amount of current from a first power supply (ELVDD) to a second power supply (ELVSS) via an organic light-emitting diode (OLED). Also included are a second (M2) and a fourth transisitors (M4) which are supplied with a scan signal (Si) of a present scan line, the second transistor (M2) supplying a data signal to a first node (N1) of the drive transistor (MD) and the fourth transistor (M4) placing the drive transistor in a diode-connected state. Fifth (M5) and sixth transistors (M6) are turned off in response control signals (Ei). The fifthe transistor is between the first node (N1) and the first power supply (ELVDD) and the sixth transistor (M6) is between the driving transistor (MD) and the OLED. A third transistor (M3) is turned on by a scan signal on a prior scan line (Si-1) and supplies a voltage of a third power supply (Vint1) to the gate electrode of the drive transistor (MD). A first transistors (M1) is also turned on by a scan signal (Si) on a present scan line and supplies a voltage of a fourth power supply (Vint2) to the OLED. The first (M1) and third (M3) transistors receive voltages of their respective power supplies through different power lines on different layers.

    摘要: A display device includes a display portion defining a display area and including a plurality of pixels, a scan driver disposed in a non-display area that is outside of the display area, and a plurality of scan connection lines. Each of the pixels is connected to a scan line from among a plurality of scan lines and a data line from among a plurality of data lines. The scan connection lines connect the scan driver to the scan lines. Each of the scan connection lines is connected to one of the scan lines through a contact hole disposed in at least one insulating layer, which is disposed between the scan lines and the scan connection lines in a cross-sectional view.
