Abstract

A display device includes: first sub-pixels commonly connected to a first global data line, each including a first light emitting element to emit light of a first color; and second sub-pixels commonly connected to a second global data line different from the first global data line, each including a second light emitting element to emit light of a second color different from the first color. At least one of the first sub-pixels includes: a first circuit to supply a driving current to the first light emitting element based on a first global data voltage received from the first global data line; a second circuit to control a supply period of the driving current based on a data voltage received from a data line; and a test transistor including a first electrode connected to an anode of the first light emitting element, and a second electrode connected to the data line.
