Abstract

A display device of the present disclosure includes: an organic EL layer deposited on a circuit unit formed on a substrate via an insulating film; a cathode electrode deposited on the organic EL layer; a groove formed along a direction of arrangement of pixels between the pixels in the insulating film; and a contact electrode that is provided at a bottom of the groove and receives a predetermined potential. Moreover, the cathode electrode is electrically connected to the contact electrode in the groove.

Claims (13)

1. A display device comprising:

an organic EL layer deposited on a circuit formed on a substrate via an insulating film;

a cathode electrode deposited on the organic EL layer;

a groove formed along a direction of arrangement of pixels between the pixels in the insulating film; and

a contact electrode that is provided at a bottom of the groove and receives a predetermined potential;

an auxiliary electrode arranged on a side wall of the groove and directly electrically connecting the cathode electrode and the contact electrode, wherein

the cathode electrode is electrically connected to the contact electrode in the groove.

2. The display device according to claim 1 , wherein

a drive circuit of a light-emitting unit including the organic EL layer is formed on a semiconductor substrate.

3. An electronic apparatus including a display device according to claim 1 .

4. The electronic apparatus according to claim 3 , wherein

a drive circuit of a light-emitting unit including the organic EL layer is formed on a semiconductor substrate.

5. The display device according to claim 1 , wherein the auxiliary electrode extends from a first end to a second end opposite the first end, the first end contacting the contact electrode and the second end contacting the sidewall of the groove.
