Abstract

A pixel includes: a driving transistor including a gate electrode coupled to a first node, a first electrode coupled to a second node, and a second electrode coupled to a third node; a first initialization transistor coupled between the first node and a first initialization voltage line, and including a gate electrode coupled to a scan line, where the first initialization voltage line is configured to supply a first initialization voltage; a first emission control transistor coupled between a fourth node and a fifth node and including a gate electrode coupled to the first node; a second emission control transistor coupled between the third node and the fifth node and including a gate electrode coupled to an emission control line; and a light-emitting element coupled between the fourth node and a driving low voltage line. The driving transistor and the first emission control transistor are different types of transistors.
