摘要：
In an organic electroluminescence (EL) display, a TFT (40) and an organic EL element (60) are formed on an insulating substrate (10) such as a glass substrate. The contact portion between the first electrode region (e.g. the source 43s) of the active layer (43) of the TFT (40) and the organic EL element (60) is formed of a laminated structure. The laminated structure is formed of the structure stacked in layers with p-si forming the source (43s), a refractory metal (Mo), aluminum, a refractory metal (Mo), and ITO forming the anode 61. The reliable contact between the source 43s and the anode 61 can prevent variations in brightness and early degradation in characteristic of the TFT 40 and the organic EL element 60.
