Abstract
Provided is an organic light emitting display device including: a display unit including a plurality of pixels, each pixel of the pixels including an organic light emitting diode; and a test circuit configured to apply a first signal and a second signal to the display unit and to receive a third signal from the display unit. The test circuit is configured to determine whether or not the display unit is in a normal state based on a voltage level of the third signal when the first and second signals have a first level.
