Problems solved by technology
In addition to the organic light-emitting materials of organic light-emitting diodes that are highly sensitive to moisture and oxygen and must be properly protected and isolated, it has been empirically found that thin-film transistors used as driving elements will also be exposed to high humidity and high temperatures. Causes an increase in leakage current (off current), which degrades the device characteristics of the thin film transistor device and cannot normally drive the organic light emitting diode device

The invention discloses a pixel structure of an electroluminescence display panel and a manufacturing method for the same. The pixel structure includes a substrate, a display driving structure, a plane structure and an electroluminescence element. The display driving structure is arranged on the substrate. The display driving structure includes a driving element. The plane structure is arranged on the substrate and includes an upper surface covering the driving element and a side wall. And the plane structure has a contact hole from which the driving element is exposed. The electroluminescence element is disposed on the plane structure. The electroluminescence element is arranged on the plane structure and includes an anode, a light emitting layer and a cathode. The anode covers the upper surface of the plane structure and surrounds the side wall of the plane structure. The anode extends into the contact hole and is then connected with the driving element electrically. The light emitting layer is arranged on the anode and the cathode is arranged on the light emitting layer.
