Abstract:
1. An EL display device comprising: plural pixels formed over a substrate; a switching element formed in each of the plural pixels and including at least one thin film transistor formed over the substrate, the thin film transistor comprising: a semiconductor island formed over the substrate, the semiconductor island having at least one pair of impurity regions with a channel region interposed therebetween; a gate electrode formed adjacent to the channel region with a gate insulating film interposed therebetween, a first insulating film formed over the thin film transistor; a second insulating film formed over the first insulating film; an organic resin film formed on the second insulating film; and a pixel electrode formed over the organic resin film and electrically connected to one of the impurity regions, wherein the first insulating film comprises a material selected from the group consisting of silicon nitride and silicon oxynitride, wherein the second insulating film comprises a material selected from the group consisting of silicon nitride, silicon oxide and silicon oxynitride.
