Abstract
A display device includes: an organic EL layer formed over a circuit section formed over a substrate, an insulating layer interposed between the circuit section and the organic EL layer; a cathode electrode formed over the organic EL layer in common for all pixels; and a contact electrode that is provided at an outer peripheral portion of an effective pixel region and that electrically connects the cathode electrode and the circuit section. In the display device, the cathode electrode is electrically connected to the contact electrode, on an inner side as compared to an end surface of a film formation area of the organic EL layer.
