Abstract

According to an embodiment, a liquid crystal display apparatus includes a plurality of sense amplifiers for amplifying respective potential differences between a plurality of positive-polarity pixel drive voltages read out from a plurality of pixels of a row to be inspected to a plurality of first data lines and a plurality of negative-polarity pixel drive voltages read out from the plurality of pixels of the row to be inspected to a plurality of second data lines, each of the pixels including a switch transistor for switching whether a positive-polarity pixel drive voltage applied to a pixel drive electrode is output to a corresponding first data line, and a switch transistor for switching whether a negative-polarity pixel drive voltage applied to the pixel drive electrode is supplied to a corresponding second data line.
