Abstract

A method of inspecting a display panel includes testing a pixel circuit including a plurality of transistors and a capacitor in the display panel. The testing of the pixel circuit includes: providing a first test voltage to a first node to which a first electrode of the capacitor is connected, providing a second test voltage different from the first test voltage to a second node to which a second electrode of the capacitor is connected, and detecting a defect in the pixel circuit through a test transistor connected to the first node among the plurality of transistors.
