Abstract
A display apparatus includes a substrate and a plurality of pixels disposed on the substrate. Each pixel includes a gate electrode on the substrate, a common electrode insulated from the gate electrode on the substrate, a first insulating layer covering the gate electrode and the common electrode, a semiconductor pattern disposed on the first insulating layer to overlap with the gate electrode, source and drain electrodes disposed on the semiconductor pattern and spaced apart from each other, and a pixel electrode disposed on the first insulating layer to cover the drain electrode and form an electric field with the common electrode. The display apparatus may be manufactured by first to fourth photolithography processes using first to fourth masks, and the first mask may be a slit mask or a diffraction mask.
