| 1. A display device comprising:
a first substrate;
a plurality of organic emitting elements on the first substrate, each of the organic emitting elements including an anode,
an organic emitting layer on the anode, and a cathode on the organic emitting layer, the organic emitting elements sharing
the cathode;
an insulation film exposing a part of the anode and covering an edge of the anode of each of the organic emitting elements;
and
a sealing film covering the organic emitting elements and the insulation film, the sealing film including a first barrier
layer, a base layer including silicon oxide or amorphous silicon on the first barrier layer, an organic layer on the base
layer, and a second barrier layer on the base layer and the organic layer, a first thickness of the first barrier layer being
thicker than a second thickness of the base layer, wherein the first barrier layer includes SiN or SiON, and the second barrier
layer includes SiN or SiON,
wherein the sealing film includes a first region where the first barrier layer, the base layer, and the second barrier layer
are laminated and the second barrier layer is in physical contact with the base layer; and a second region where the first
barrier layer, the base layer, the organic layer, and the second barrier layer are laminated.
