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.
