Abstract: A display device includes a sub-pixel connected to a scan write line, a first data line, and a second data line. The sub-pixel includes a light emitting element, a first pixel driving unit configured to generate a control current according to a first data voltage of the first data line, a second pixel driving unit configured to generate a driving current applied to the light emitting element according to a second data voltage of the second data line, and a third pixel driving unit configured to apply the driving current to the light emitting element according to the control current of the first pixel driving unit. The first pixel driving unit includes a first transistor to generate the control current according to the first data voltage, a second transistor configured to apply the first data voltage of the first data line to a first electrode of the first transistor.
