Display device with patterned intermediate layer on auxiliary electrode and method of manufacturing the same

A display device comprising:

• an organic insulating layer disposed on a substrate and having an opening;
• a first electrode disposed on the organic insulating layer;
• an auxiliary electrode disposed on the organic insulating layer, the auxiliary electrode having a first portion overlapping the opening of the organic insulating layer in a plan view;
• a bank layer including a first bank opening and a second bank opening, the first bank opening overlapping the first electrode in the plan view, and the second bank opening overlapping the first portion of the auxiliary electrode in the plan view;
• an intermediate layer disposed on the first electrode and the auxiliary electrode, the intermediate layer including a hole exposing a portion of the auxiliary electrode in the opening of the organic insulating layer;
• and
• a second electrode disposed on the intermediate layer and overlapping the first electrode and the auxiliary electrode in the plan view, the second electrode electrically contacting the auxiliary electrode through the hole of the intermediate layer,
• wherein the intermediate layer further comprises:
• a first area adjacent to the hole of the intermediate layer, a first thickness of the first area varying in the first area;
• a second area adjacent to and extending from the first area and within the opening of the organic insulating layer, a second thickness of the second area varying in the second area, the second thickness having a maximum point at which the intermediate layer has a greatest thickness;
• and
• a third area disposed at an outer edge of the second area and within the opening of the organic insulating layer, the third area having a third thickness that is uniform.

A method of manufacturing a display device, the method comprising:

• forming an organic insulating layer having an opening on a substrate;
• forming a first electrode on the organic insulating layer;
• forming an auxiliary electrode having a first portion overlapping the opening of the organic insulating layer in a plan view, on the organic insulating layer;
• forming a bank layer including a first bank opening and a second bank opening, the first bank opening overlapping the first electrode in the plan view, and the second bank opening overlapping the first portion of the auxiliary electrode in the plan view;
• forming an intermediate layer on the first electrode and the auxiliary electrode;
• forming a hole of the intermediate layer in the opening of the organic insulating layer by irradiating a laser to the intermediate layer, the hole of the intermediate layer exposing a portion of the auxiliary electrode;
• removing a portion of a first area of the intermediate layer around the hole of the intermediate layer and forming a second area of the intermediate layer to protrude by irradiating the laser to the intermediate layer, the second area being extended to the first area and within the opening of the organic insulating layer;
• and
• forming a second electrode on the intermediate layer to electrically contact the auxiliary electrode through the hole of the intermediate layer,
• wherein a third area of the intermediate layer is disposed at an outer edge of the second area and within the opening of the organic insulating layer, the third area having a third thickness that is uniform.
