Abstract
EL display has a luminescence unit having a luminescence layer being disposed between a pair of electrodes and a thin film transistor array unit controlling luminescence of the luminescence unit. An interlayer insulation film is disposed between the luminescence unit and the transistor array unit. An anode of the luminescence unit is connected electrically to the thin film transistor array via a contact hole of the interlayer insulation film. The thin film transistor array further has a current supplying relaying electrode that is connected to the anode of the luminescence unit via the contact hole of the interlayer insulation film. A diffusion prevention film is formed on the boundary face of the anode of the luminescence unit and the relaying electrode.
