摘要:
An organic light emitting display (OLED) and method of fabricating the same are provided having a reduced number of photolithography and etching steps. The method includes a source electrode and a drain electrode being formed over a substrate, and at least one insulating layer being formed over the source electrode and drain electrode. After the insulation layer is formed, a reflecting layer pattern is formed. A via contact hole is formed through the insulating layer using the reflecting layer pattern as an etching mask. Multiple insulating layers may be formed and have a via contact hole etched therethrough in one etching step using the reflecting layer pattern as a mask. Alternatively, each insulating layer may have a via contact hole separately etched therethrough, with the last layer being etched using the reflective layer pattern as a mask. Consequently, the number of photolithography and etching steps is reduced thereby leading to higher manufacturing yield and lower manufacturing cost.
