Abstract
A method of manufacturing a display substrate may include the following steps: forming a drain electrode on a pixel area of a substrate; forming a pad electrode on a pad area of the substrate; forming an inorganic insulation layer that covers the drain electrode and the pad electrode; forming an organic insulation member that has a first thickness at the pixel area of the substrate, has a second thickness less than the first thickness at the pad area of the substrate, exposes a first portion of the inorganic insulation layer on the drain electrode, and exposes a second portion of the inorganic insulation layer on the pad electrode; removing the first portion of the inorganic insulation layer and the second portion of the inorganic insulation layer; and partially removing the organic insulation member.
