Provided are a display device and a method of manufacturing the display device. The display device includes a substrate, a transistor, a first electrode connected with the transistor, a bank layer covering an edge of the first electrode, including an opening overlapping the first electrode, and a first insulating layer, wherein a top surface of the first electrode includes a first surface portion overlapping the opening of the bank layer, a second surface portion having a vertical distance from the substrate smaller than a vertical distance of the first surface portion from the substrate, a first slope portion between the first surface portion and the second surface portion, the first slope portion inclined downward with respect to the first surface portion, and a second slope portion between the first slope portion and the second surface portion, the second slope portion inclined downward from the edge of the first electrode.

Display apparatus and method of manufacturing the same

A display apparatus includes a substrate with a display area and a peripheral area surrounding the display area, a thin-film transistor disposed on the display area of the substrate, a pad unit disposed on the peripheral area of the substrate, a first insulating layer disposed on the display area of the substrate and exposing the pad unit, the first insulating layer including a first portion disposed on the thin-film transistor, a second portion, and a third portion between the first portion and the second portion, and a light-emitting device disposed on the first portion of the first insulating layer and electrically connected to the thin-film transistor. A top surface of the first insulating layer includes a first top surface of the first portion, a second top surface of the second portion, and a connecting surface of the third portion. The first top surface of the first portion is higher than the second top surface of the second portion. The connecting surface connects the first top surface and the second top surface with each other and is sloped.

A display apparatus includes a substrate including a display area and a peripheral area; a thin-film transistor disposed on the substrate and including a semiconductor layer; a conductive layer disposed between the substrate and the semiconductor layer and including a pad electrode disposed in the peripheral area; a first insulating layer disposed between the conductive layer and the semiconductor layer and including a first opening exposing at least a part of an upper surface of the pad electrode; and a second insulating layer disposed on the thin-film transistor and including a second opening coinciding with the first opening, wherein an opening area of the second opening of the second insulating layer is greater than an opening area of the first opening of the first insulating layer.

A display apparatus includes a substrate including a display area and a peripheral area adjacent to the display area, a thin-film transistor located in the display area of the substrate and including a semiconductor layer and a gate electrode overlapping a channel region of the semiconductor layer, a conductive layer disposed between the substrate and the semiconductor layer and including a first electrode located in the display area of the substrate and a pad electrode located in the peripheral area of the substrate, and a first insulating layer disposed between the conductive layer and the semiconductor layer and having a first opening that exposes at least a portion of an upper surface of the pad electrode.
