Display device and capacitor plates including different size holes

A display device includes a scan line extending in a direction, a data line and a driving voltage line extending in another direction, a transistor electrically connected to the driving voltage line and including a first gate electrode and a first semiconductor layer, a second transistor electrically connected to the scan and data lines and including a second gate electrode and a second semiconductor layer, a first capacitor electrically connected to the first transistor and including first and second capacitor plates, and a second capacitor including a third capacitor plate electrically connected to the first transistor and a fourth capacitor plate electrically connected to the second transistor. The second capacitor plate includes a first hole overlapping the first capacitor plate, the fourth capacitor plate includes a second hole overlapping the third capacitor plate, and a size of the second hole is different from that of the first hole.
