Abstract
A method for inspecting a display device (which includes a pixel electrode and a touch sensor overlapping the pixel electrode) includes: adjusting an impedance value of a variable impedance circuit of an inspection apparatus according to a model of the display device; driving a power source generator of the inspection apparatus; supplying a pixel voltage to the pixel electrode through an output terminal connected to the variable impedance circuit; driving the touch sensor; and detecting a defect related to the pixel electrode based on sensing signals output from the touch sensor.
