Abstract:
1. A method of manufacturing an organic light-emitting display apparatus, the method comprising: a first mask process comprising forming an amorphous silicon (a-Si) layer on a substrate having a first area and a second area, partially crystallizing the a-Si layer to convert the a-Si layer into a partially crystallized Si layer, re-crystallizing the partially crystallized Si layer on the first area to form a poly-Si layer, patterning the poly-Si layer on the first area to form active layers of TFTs, and patterning the partially crystallized Si layer on the second area to form lower electrodes of capacitors; a second mask process comprising forming a first insulating layer and a transreflective metal on the substrate to cover the active layers and the lower electrodes of the capacitors and patterning the transreflective metal to form pixel electrodes; a third mask process comprising sequentially forming a transparent conductive layer and a first metal layer on the substrate to cover the pixel electrodes and patterning the transparent conductive layer and the first metal layer to form first and second gate electrodes of the TFTs and first and second upper electrodes of the capacitors; a fourth mask process comprising forming a second insulating layer to cover the pixel electrodes, the first and second gate electrodes, and the first and second upper electrodes and patterning the second insulating layer to form openings exposing the pixel electrodes, source and drain areas of the active layers, and the second upper electrodes; a fifth mask process comprising forming a second metal layer to cover the pixel electrodes and the openings and patterning the second metal layer to form source and drain electrodes; and a sixth mask process comprising forming a third insulating layer to cover the source and drain electrodes and patterning the third insulating layer to expose the pixel electrodes.
