Abstract: A display apparatus includes: a substrate; a source electrode, a drain electrode, and first electrodes disposed on the substrate and spaced apart from each other; a first layer covering the source electrode, the drain electrode, and the first electrodes; a semiconductor layer disposed on the first layer; a source connection electrode contacting the source electrode through a first hole in the first layer to electrically connect the source electrode and the semiconductor layer to each other; a drain connection electrode contacting the drain electrode through a second hole in the first layer to electrically connect the drain electrode and the semiconductor layer to each other; and a pixel electrode disposed above the first layer and overlapping the first electrodes including first projections overlapping the first electrodes and first recesses between the first projections.
