Abstract
In manufacturing of an organic electroluminescence (EL) display device, after first electrodes are formed on a substrate, insulating films are formed on the first electrodes except regions corresponding to light emitting portions. Spacers are formed on the insulating films, and overhanging portions are formed so as to overhang the spacers. Thus, element isolating structure portions for isolating organic EL elements are formed. Then, organic EL films, second electrodes, and protecting films are sequentially formed between the spacers. In the thus formed light emitting portions of the organic EL display device, the bending angle of a bending portion of a pattern of the element isolating structure portion is larger than 90.degree..
