Abstract
An organic light emitting display in which each pixel has a driving thin film transistor for adjusting the current flowing through an organic light emitting diode based on a voltage applied to a gate electrode, includes the gate electrode of the driving thin film transistor; a signal line adjacent to the gate electrode of the driving thin film transistor; and a first shielding electrode located above the gate electrode of the driving thin film transistor, with a first insulating layer therebetween, wherein the first shielding electrode extends further towards the signal line than the gate electrode of the driving thin film transistor.
