Abstract
A pixel circuit includes: a main circuit including: a driving transistor that includes a gate terminal connected to a first node, a first terminal connected to a second node, and a second terminal connected to a third node; and an organic light-emitting element connected to the driving transistor and configured to control the organic light-emitting element by controlling a driving current corresponding to a data signal applied via a data line to flow into the organic light-emitting element; and a sub circuit including: a first compensation transistor that includes a gate terminal configured to receive a first gate signal, a first terminal connected to the first node, and a second terminal connected to a fourth node; and a second compensation transistor that includes a gate terminal configured to receive a second gate signal, a first terminal connected to the fourth node, and a second terminal connected to the third node.
