Abstract
An organic EL display device comprises a first TFT ( ) for switching; a second TFT ( ) for driving an organic EL element; and an organic EL element ( ) having an anode ( ), a cathode ( ), an emissive element layer ( ) interposed between both electrodes. Additionally, a first storage capacitor electrode ( ) comprising Cr and a second storage capacitor electrode ( ) also functioning as a p-Si film which is a source ( s) of the first TFT ( ) constitute a first storage capacitor ( ) via a gate insulating film ( ), while said second storage capacitor electrode ( ) and a third storage capacitor electrode ( ) formed by extending a part of a power supply line ( ) for causing the organic EL element ( ) to emit light are arranged to be opposed to each other via an interlayer insulating film to form a second storage capacitor ( ). Thus, it is possible to implement a light emissive display device which achieves bright display while sufficiently holding charges within one pixel without reducing the aperture ratio.
