    Abstract: A display device may include a plurality of pixels each including a light emitting element. A first scan line and a second scan line, are disposed in each of the pixels. A data line is disposed in each of the pixels. A power line is disposed in each of the pixels. A reference voltage line is disposed in each of the pixels. A first transistor controls a current of the light emitting element. A second transistor is connected between the data line and a first gate electrode of the first transistor. A third transistor is connected between the reference voltage line and a first electrode of the first transistor. A fourth transistor is connected between the power line and a second electrode of the first transistor. The fourth transistor may be a transistor of a type different from that of the first to third transistors.
