Abstract
A display device inspection method includes: checking connection failures of light emitting elements included in a pixel and connected in series based on a first control signal, a second control signal, and a voltage of an initialization power source, wherein the pixel comprises: a pixel circuit controlling a current flowing from a first power source to a second node in response to a voltage of a first node; a first light emitting element connected to the second node; a first transistor controlling the voltage of the initialization power source supplied to the second node; a second light emitting element electrically connected between the first light emitting element and a second power source; and a second transistor having a first electrode connected to a third node between the first light emitting element and the second light emitting element, and a gate electrode connected to a first inspection control line.
