ABSTRACT:
An object is to provide a display device, in a part of which a monitor light emitting element is provided and in which an anode and a cathode of the monitor light emitting element are prevented from short-circuiting in an early stage and over time by using a circuit which corrects a voltage or a current to be supplied to a light emitting element in consideration of electrical property fluctuation of the monitor light emitting element, and a method for inspecting the display device. A monitor light emitting element is provided, which is electrically connected to a monitor line for supplying a current is provided, and a circuit is provided, which electrically disconnects the monitor light emitting element when an anode and a cathode of the monitor light emitting element are short-circuited in an early stage or over time. Further, a circuit for checking circuit operation before or after a step of providing the monitor light emitting element is provided.
