Abstract
A display device includes: a thin film transistor; and a wiring layer; the thin film transistor including a control electrode, a semiconductor layer facing the control electrode, a first electrode made of a light transmissive material and electrically connected to the semiconductor layer, and a second electrode including a metal film having resistance lower than that of the light transmissive material, the second electrode being electrically connected to each of the semiconductor layer and the wiring layer, wherein a difference in ionization tendency between a material configuring the metal film and a conductive material configuring a part or whole of the wiring layer is smaller than a difference in ionization tendency between the light transmissive material and the conductive material.
