ABSTRACT:
A driving circuit for an organic light emitting display apparatus includes first and second switching elements and a driving element. The first switching element is controlled by a scan signal supplied from a scan line. The second switching element is controlled by the scan signal. The driving element provides an end of an organic electroluminescent element with a first reference voltage via the second switching element. The driving element has amorphous silicon thin film transistors so that the manufacturing cost of the organic light emitting display apparatus may be reduced.
