Abstract

Separation of wirings formed on an organic passivation film is prevented in an organic EL display device or a liquid crystal display device. The organic EL display device includes a TFT formed on a substrate and an organic passivation film formed to cover the TFT. An intermediate film containing SiO or SiN is formed to cover the organic passivation film. An insulation film formed with an organic material is formed on the intermediate film. A reflective electrode is formed on the intermediate film. The reflective electrode is connected to the TFT via a through-hole formed in the organic passivation film and a through-hole formed in the intermediate film.
