Abstract

A display device comprising a pixel portion having a thin film transistor using silicon as a semiconductor layer and a pixel electrode connected to the thin film transistor, wherein: said pixel electrode having a first transparent electrically conductive film electrically connected to said semiconductor layer and a second transparent electrically conductive film disposed on the first transparent electrically conductive film; said first transparent electrically conductive film comprises an oxide layer of a first metal having an oxidation potential lower than that of silicon; and said second transparent electrically conductive film comprises an oxide layer of a second metal having an oxidation potential higher than that of silicon. Also claimed is a process for fabricating the display device.
