Display device and manufacturing method for the same

A display device comprising:

• a base layer;
• a circuit layer disposed on the base layer;
• a pixel definition layer which is disposed on the circuit layer and includes an inorganic protective layer and an organic layer disposed on the inorganic protective layer, and in which an opening is defined, the pixel definition layer comprising:
• a first portion directly disposed on the circuit layer;
• a second portion which is spaced apart in a thickness direction in the circuit layer and disposed on one side of the first portion, and in which an upper opening exposing the inorganic protective layer and the organic layer;
• and
• a third portion disposed between the first portion and the second portion, and having a lower opening exposing the inorganic protective layer;
• a light-emitting element including a first electrode disposed on the circuit layer, a functional layer disposed on the first electrode, and a second electrode disposed on the functional layer;
• and
• an encapsulation layer disposed on the light-emitting element, the encapsulation layer comprising:
• an auxiliary electrode layer which covers the light-emitting element disposed in the lower opening, the inorganic protective layer exposed in the lower opening, and the light-emitting element disposed in the upper opening;
• an encapsulation organic film disposed on the auxiliary electrode layer;
• and
• an upper inorganic film disposed on the encapsulation organic film.

A display device comprising:

• a base layer;
• a circuit layer disposed on the base layer;
