ABSTRACT:
A liquid crystal display having a circuit to protect against static electricity makes passages in which static electricity can flow, by connecting diodes between a plurality of data lines, gate lines and a plurality of shorting lines in the same or opposite direction as current flow. Accordingly, the circuit protects a liquid crystal display from static electricity. A testing method of display quality checks whether the data lines and the gate lines are shorted or not by applying signals to the gate lines and the data lines through shorting lines and making mutually inverted output voltages appear in contiguous pixels.
