Abstract:
1. A method of manufacturing a display apparatus, the method comprising: forming a first insulating layer on top of a substrate; patterning the first insulating layer to form an opening that exposes the substrate and also to form a concavo-convex insulating layer and a sacrificial insulating layer thicker than the concavo-convex insulating layer, wherein the concavo-convex insulating layer has an upper surface comprising a concavo-convex area and has one or more side surfaces adjacent to the upper surface; forming a metal layer on the substrate's portion exposed by the opening, over the upper surface and the one or more side surfaces of the concavo-convex insulating layer, and on an upper surface of the sacrificial insulating layer; removing the sacrificial insulating layer to form a first storage electrode that covers the concavo-convex area of the upper and at least one of the one or more side surfaces of the concavo-convex insulating layer and to form a gate electrode on the substrate's portion exposed by the opening; forming a second insulating layer on top of the gate electrode and on top of the first storage electrode; forming a semiconductor layer on top of the second insulating layer and over the gate electrode; forming a source/drain electrode on the semiconductor pattern; and forming a third insulating layer on top of the source/drain electrode and the semiconductor layer.
