Abstract
A display device includes a substrate, a first transistor, a second transistor and a conductive connection portion disposed on the substrate. The first transistor is electrically connected to the gate electrode of the second transistor through the conductive connection portion. An insulating layer is disposed on the conductive connection portion. A pixel electrode is disposed on the insulating layer and is electrically connected to the second transistor. The pixel electrode is at least partially overlapped with the conductive connection portion. A light-emitting element is disposed on the pixel electrode. The conductive connection portion and the pixel electrode form a capacitor. The capacitor has an equivalent permittivity and a thickness. The ratio of the equivalent permittivity to the thickness is in a range from 0.4*(1E+5)F/m^2 to 296.48*(1E+5)F/m^2.
