Abstract
An object of the present invention is to provide a semiconductor device having high operation characteristic and reliability. The measures taken are: A pixel capacitor is formed between an electrode comprising anodic capable material over an organic resin film, an anodic oxide film of the electrode and a pixel electrode above. Since the anodic oxide film is anodically oxidized by applied voltage per unit time at 15V/min, there is no wrap around on the electrode, and film peeling can be prevented.
