Abstract

A pixel includes a light emitting element, a driving switching element and a first compensation switching element and a second compensation switching element. The driving switching element is which applies a driving current to the light emitting element. The first compensation switching element and the second compensation switching element are connected between a control electrode of the driving switching element and an output electrode of the driving switching element. The first compensation switching element and the second compensation switching element are connected to each other in series. The driving switching element is a P-type transistor. The first compensation switching element is an N-type transistor. The second compensation switching element is a P-type transistor.
