Abstract
In an organic electroluminescence (EL) display, a TFT ( ) and an organic EL element ( ) are formed on an insulating substrate ( ) such as a glass substrate. The contact portion between the first electrode region (e.g. the source ) of the active layer ( ) of the TFT ( ) and the organic EL element ( ) is formed of a laminated structure. The laminated structure is formed of the structure stacked in layers with p-si forming the source ( ), a refractory metal (Mo), aluminum, a refractory metal (Mo), and ITO forming the anode . The reliable contact between the source and the anode can prevent variations in brightness and early degradation in characteristic of the TFT and the organic EL element
