1. A display device comprising:
a display panel comprising:
an organic layer;
a thin film transistor disposed on the organic layer;
an organic light-emitting device connected to the thin film transistor, the organic light-emitting device comprising:
an anode,
a cathode, and
an emission layer between the anode and the cathode; and
an inorganic layer between the organic layer and the thin film transistor;
a plurality of organic layers stacked around the inorganic layer, the thin film transistor, and the organic light-emitting device, the plurality of organic layers comprising:
the organic layer,
a first layer which covers the organic light-emitting device, the first layer being disposed opposite to the organic layer with respect to the organic light-emitting device,
an organic pixel-defining layer which defines a pixel region of the organic light-emitting device, on the organic layer, and
a second layer of the thin film transistor on the organic layer,
a light-emitting region including the organic light-emitting device, the light-emitting region provided in plural comprising light-emitting regions; and
an accommodation hole extended through the inorganic layer and the cathode, the accommodation hole being defined between light-emitting regions adjacent to each other among the light-emitting regions,
wherein
side surfaces of each of the organic layer, the first layer, the organic pixel-defining layer, the second layer, the inorganic layer and the cathode define the accommodation hole,
a portion of the organic layer is exposed to outside the inorganic layer, at the accommodation hole, and
a metal oxide layer is in the accommodation hole defined between the light-emitting regions adjacent to each other, the metal oxide layer contacting the portion of the organic layer and the side surfaces each of the organic laver, the first layer, the organic pixel-defining laver, the second layer, the inorganic layer and the cathode.
