ABSTRACT:
An object of the present invention is to provide an EL display device, which has a high operating performance and reliability. A third passivation film45is disposed so as to be in contact with an EL element203which comprises a pixel electrode (anode)46, an EL layer47and a cathode48, to make a structure in which heat generated by the EL element203is radiated. Further, the third passivation film45prevents alkali metals within the EL element203from diffusing into the TFTs side, and prevents moisture and oxygen of the TFTs side from penetrating into the EL element203. More preferably, heat radiating effect is given to a fourth passivation film50to make the EL element203to be enclosed by heat radiating layers.
