Patent ID: 7525334

Claim:
A defective pixel examination method for use with a liquid-crystal display device including a plurality of pixel sections each having a pixel transistor, a capacitive element connected to an output electrode of the pixel transistor, and a liquid-crystal section for performing gradation display based on a voltage held in the capacitive element, the defective pixel examination method comprising the steps of: applying different voltages to a capacitive element of a first pixel section and a capacitive element of a second pixel section among the plurality of pixel sections; turning on a switch provided between an input electrode of a pixel transistor in the first pixel section and an input electrode of a pixel transistor in the second pixel section and short-circuiting the input electrode of the first pixel transistor and the input electrode of the second pixel transistor; reading a voltage of the capacitive element of the first pixel section and a voltage of the capacitive element of the second pixel section; and detecting a defect of a pixel section on the basis of the result of the comparison between the voltage of the capacitive element of the first pixel section and the voltage of the capacitive element of the second pixel section.
