Abstract

A fabrication method of a pixel structure of an electroluminescent display panel includes the following steps. A substrate is provided. A first anode, a second anode and a third anode are formed in a first sub-pixel region, a second sub-pixel region and a third sub-pixel region respectively. A first organic light-emitting layer is formed in the first sub-pixel region by using a first fine metal mask. A second organic light-emitting layer is formed in the second sub-pixel region and the third sub-pixel region by using a second fine metal mask. A first cathode, a second cathode and a third cathode are formed in the first sub-pixel region, the second sub-pixel region, and the third sub-pixel region, respectively. The first micro cavity in the first sub-pixel region, the second micro cavity in the second sub-pixel region and the third micro cavity have different cavity lengths.
