Abstract:
A display apparatus includes a plurality of pixels each including an organic light emitting device and a pixel driving circuit. The pixel driving circuit includes a driving transistor controlling a driving current flowing in the organic light emitting device and a first, second, third, fourth, and fifth switching transistor, the third switching transistor selectively connecting a second node which is a drain electrode of the driving transistor to a third node which is a gate electrode of the driving transistor. The third switching transistor differs from a type of each of the driving transistor and the first, second, fourth, and fifth switching transistors. Accordingly, even when the organic light emitting display apparatus is driven at a low frequency, a bezel area is reduced, and a high resolution of a display panel is realized.
