PROBLEM TO BE SOLVED: To obtain an active matrix 4-terminal TFT-EL device in which an organic material is used as an EL medium by using a thin film transistor formed by polycrystalline silicone. SOLUTION: A first thin film transistor (TFT1) formed from polycrystalline silicone is disposed on th upper surface of a substrate. A source electrode of TFT1 is electrically connected to a source path. A second TFT 2 is disposed on the upper surface of a substrate, and a gate electrode is electrically connected to a drain electrode of the first TFT1. A storage condenser is disposed on the upper surface of the substrate. An anode layer is electrically connected to a drain electrode of the TFT2. A dielectric passivation layer is accumulated on at least the source of the TFT1. The dielectric passivation layer is etched to provide an opening on a display anode. Further, an organic electroluminescence(EL) layer is directly disposed on the upper surface of an anode layer. Subsequently, a cathode layer is directly accumulated on the upper layer of the organic EL layer.
