Abstract: PROBLEM TO BE SOLVED: To provide an organic electroluminescent element for simultaneously connecting power supply wiring to an adjacent pixel. SOLUTION: In this organic electroluminescent element for improving particularly an opening rate and a method for manufacturing the element, the organic electroluminescent element is formed so that the positions of drive elements formed in the pixels adjacent to each other are positioned close to each other to simultaneously receive signals with one power supply line. Thus, since the number of the power supply lines can be halved as compared with conventional elements, defective wiring can be prevented by improving the opening rate and brightness of the organic electroluminescent element.
