Abstract
A display device includes: a first pixel driver to generate a control current; a second pixel driver to generate a driving current, and control a period during which the driving current flows, based on the control current; and a light-emitting element connected to the second pixel driver to receive the driving current. The first pixel driver includes: a first transistor to generate the control current based on a first data voltage; and a second transistor to provide the first data voltage to a first electrode of the first transistor based on a scan write signal from a scan write line. The second pixel driver includes: a third transistor to generate the driving current based on the control current; and a fourth transistor to provide a second data voltage to a first electrode of the third transistor based on a scan write signal from the scan write line.
