Abstract
Official abstract text for this publication.
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 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 is electrically connected to each of the semiconductor layer and the wiring layer. 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.
