Display device and electronic device including the same

An electronic device comprising:

• a housing;
• and
• a display device accommodated in the housing, wherein the display device displays an image,
• wherein the display device includes:
• a light emitting element;
• a first transistor which applies a driving current to the light emitting element;
• a first capacitor including a first electrode electrically connected to a gate electrode of the first transistor and a second electrode;
• a second transistor which applies a data voltage to the second electrode of the first capacitor in response to a write gate signal;
• a third transistor which diode-connects the first transistor in response to a compensation gate signal;
• and
• a fourth transistor which applies an initialization voltage to an anode of the light emitting element in response to an initialization gate signal,
• wherein a channel of the first transistor and a channel of the third transistor are in a first semiconductor layer, and
• wherein a channel of the second transistor and a channel of the fourth transistor are in a second semiconductor layer arranged on the first semiconductor layer.
