    摘要： An object of the present invention is to provide an EL display device, which has a high operating performance and reliability.A third passivation film 45 is disposed under an EL element 203 which comprises a pixel electrode (anode) 46, an EL layer 47 and a cathode 48, to make a structure in which heat generated by the EL element 203 is radiated. Further, the third passivation film 45 prevents alkali metals within the EL element 203 from diffusing into the TFTs side, and prevents moisture and oxygen of the TFTs side from penetrating into the EL element 203. More preferably, heat radiating effect is given to a fourth passivation film 50 to make the EL element 203 to be enclosed by heat radiating layers.

    摘要： A light-emitting element which emits light with high luminance and can be driven at low voltage. The light-emitting element includes n (n is a natural number of 2 or more) EL layers between an anode and a cathode, and includes a first layer, a second layer, and a third layer between an m-th (m is a natural number, 1≦m≦n−1) EL layer from the anode and an (m+1)th EL layer. The first layer functions as a charge-generation region, has hole-transport properties, and contains an acceptor substance. The third layer has electron-transport properties and contains an alkali metal or the like. The second layer formed of a metal complex having a metal-oxygen bond and an aromatic ligand is provided between the first and third layers, whereby an injection barrier at the time of injecting electrons generated in the first layer into the m-th EL layer through the third layer can be lowered.
