The gate lines extend in a first direction. The data lines extend in a second direction intersected with the first direction. The gate signal-inputting unit is formed at a first end of each of the gate lines to apply gate signals to the gate lines. The first test unit is formed at a second end of each of the gate lines opposite to the first end applying a first test signal to the gate lines. The first dummy switching unit is formed between the gate signal-inputting unit and the first test unit and transferring the first test signal to the gate lines.Field of SearchMISCELLANEOUSDUT including test circuit With identification of DUT Test of semiconductor device Liquid crystal device test Electrical excitation of liquid crystal (i.e., particular voltage pulses, AC vs. DC, threshold voltages, etc.) Defect correction or compensation WITH MEASURING OR TESTING Electrical characteristic sensed | |
