Abstract: A display apparatus includes a semiconductor layer disposed on a substrate and including a channel area, a source area and a drain area that are disposed at both sides of the channel area, and a first opening portion disposed adjacent to the source area or the drain area, and a first electrode overlapping and electrically connected to the source area or the drain area and including an edge adjacent to the first opening portion. The edge of the first electrode is concave in a direction from the first opening portion toward the source area or the drain area.

Abstract: A method of manufacturing a display device including the steps of: forming, on a first mother substrate, pixels including pixel electrodes, gate lines and data lines connected to the pixels; dividing the data lines into groups and connecting the data lines of the same group to one connection line; forming inspection electrodes on the first mother substrate overlapping a shot boundary portion of a mask, the inspection electrodes connected to a plurality of connection lines, respectively; preparing a second mother substrate; forming a common electrode on the second mother substrate; forming a mother panel including the first and second mother substrates and a liquid crystal layer therebetween; applying a first voltage to the common electrode and a second voltage to the inspection electrodes; and determining whether the inspection electrodes and the common electrode are short-circuited based on an image displayed in a display area of the mother panel.
