Abstract: A display device includes a display panel including a plurality of pixels, and a panel driver that generates a scan signal, a global signal, and data signals, and provides first and second power supply voltages to the display panel. Each pixel includes a first transistor between one of data line and a first node, the first transistor receiving the scan signal at a gate of the first transistor, a second transistor to transfer the first power supply voltage in response to the global signal, a driving transistor between the second transistor and a second node, the driving transistor having a gate connected to the first node, an organic light emitting diode between the second node and the second power supply voltage, and a storage capacitor between the first node and the second node. The driving transistor and the second transistor are different ones of P-type and N-type transistors.

Abstract: A display device includes at least one transistor. The transistor has an active pattern including a first active area and a second active area. The first active area includes a first channel area and an n-doped area contacting the first channel area. The second active area includes a second channel area and a p-doped area contacting the second channel area. A first insulation layer covers at least a portion of the active pattern. A first gate electrode is disposed on the first insulation layer and at least partially overlaps the first channel area. A second gate electrode is disposed on the first insulation layer and at least partially overlaps the second channel area. A taper angle of the second gate electrode is larger than a taper angle of the first gate electrode.
