Patent ID: 7977125

Claim:
A method of manufacturing a display apparatus, comprising: preparing a first substrate on which a pixel area, a first pad area, and a second pad area are defined; forming a gate line on the first substrate; forming a first insulating layer pattern on the gate line; forming a data line on the first substrate; forming a first contact portion that is arranged above the gate line and electrically connected to the gate line in a first peripheral area spaced apart from the first pad area to form a first test pad; testing the gate line using the first contact portion as a terminal; forming a second contact portion arranged above the first contact portion and electrically connected to the first contact portion and the gate line; forming a second insulating layer pattern on the data line; forming a pixel electrode in the pixel area; testing the gate line using the second contact portion as a terminal; and combining a second substrate on which a common electrode is formed with the first substrate.
