Abstract
An organic light emitting device includes an organic light emitting diode including an anode and a cathode, a driving transistor including a first semiconductor layer, wherein the driving transistor is electrically connected to the anode of the organic light emitting diode, and a control transistor including a second semiconductor layer including a different material from the first semiconductor layer and configured to control the driving transistor. The first semiconductor layer includes a first channel part, and first and second contact parts, and the second semiconductor layer includes a second channel part, and third and fourth contact parts. One of the first and second contact parts directly contacts one of the third and fourth contact parts.
