- forming a pixel electrode on the conductive contact element;
- forming a second substrate including a common electrode;
- and
- interposing a liquid crystal layer between the first substrate and the second substrate.
A method of manufacturing a liquid crystal display, the method comprising:
- forming a gate line, a data line, a switching element including a source electrode and a drain electrode, and a pixel electrode connected to the switching element through a contact hole, on a first substrate including a pixel area, wherein the contact hole exposes a portion of the source electrode of the switching element;
