Abstract
An organic light emitting display device includes a display panel including a plurality of pixels and a panel driver configured to generate driving signals to drive the plurality of pixels. Each of the plurality of pixels includes a first transistor, a second transistor, a storage capacitor, a third transistor, a maintain capacitor, a fourth transistor, a fifth transistor, and an organic light emitting diode. The maintain capacitor is configured to maintain a gate voltage of the first transistor during an emission period of the pixels.
