Display device

A display device comprising:

• a first pixel electrode electrically connected to a first transistor;
• a second pixel electrode electrically connected to a second transistor and formed in a same layer as the first pixel electrode;
• a first light-emitting layer formed over the first pixel electrode and overlapping the first pixel electrode;
• and
• a second light-emitting layer formed over the second pixel electrode and overlapping the second pixel electrode,
• wherein the first light-emitting layer includes a quantum-dot light-emitting layer that emits light of a first color, and
• the second light-emitting layer includes an organic light-emitting layer that emits light of a second color,
• wherein the display device further comprising:
• a first subpixel including the first pixel electrode;
• a second subpixel including the second pixel electrode;
• a signal processing circuit configured to generate a first signal corresponding to the first subpixel, and a second signal corresponding to the second subpixel in response to an input signal of the first color and an input signal of the second color;
• and
• a driver configured to perform a hold control based on the second signal, and an impulse control based on the first signal.
