More Information
Summary:An object of the present invention is to provide an EL display device having high operation performance and reliability. A third passivation film 45 is disposed under the EL element 203 comprising a pixel electrode (anode) 46, an EL layer 47 and a cathode 48, and diffusion of alkali metals from the EL element 203 formed by ink jet method into TFTs is prevented. Further, the third passivation film 45 prevents penetration of moisture and oxygen from the TFTs, and suppress degradation of the EL element 203 by dispersing the heat generated by the EL element 203.
