Abstract
A display device includes a pixel circuit on a substrate, a data line configured to transmit a data signal for the pixel circuit on the substrate, and a monitoring circuit. The pixel circuit includes a driving transistor configured to control an amount of electric current supplied to a light-emitting element, and a first switching transistor disposed between the light-emitting element and the driving transistor. The first switching transistor switches between supplying and not supplying the light-emitting element with electric current from the driving transistor. The monitoring circuit monitors a signal at a monitoring point located between the driving transistor and the first switching transistor in the pixel circuit.
