Abstract

A liquid crystal display device includes a liquid crystal panel and a driver that drives the liquid crystal panel. The driver includes a control unit that executes a display process of displaying an image on the liquid crystal panel, a touch detection process of detecting a touch on the liquid crystal panel, and a line defect determination process of determining the presence of a line defect in the liquid crystal panel. In the line defect determination process, the control unit applies a drive signal to each sensor electrode, determines whether a detection value detected from each of the sensor electrodes when the drive signal is applied meets a predetermined determination criterion, and determines that the line defect has occurred when the sensor electrodes whose detection values meet the determination criterion among the plurality of sensor electrodes are linearly distributed.
