PURPOSE: An organic EL(ElectroLuminescence) display apparatus is provided to reduce the light attenuation in the course of light emission. CONSTITUTION: An EL display apparatus includes a plurality of pixels provided over a common substrate. Each pixel comprises an EL element and a thin film transistor. The EL element further includes a transparent lower electrode, an emissive element layer including an emissive material, and an upper electrode formed to face the lower electrode via the emissive element layer. The thin film transistor for controlling light emission of the EL element, is formed below the EL element and electrically connected with the EL element. The thin film transistor includes a gate electrode(18), a silicon oxide layer(12), and a silicon active layer. In the region where the thin film transistor is not formed, the silicon oxide layer has an opening, and a moisture blocking insulating film(26), which is formed to cover the thin film transistor in a region where the thin film transistor is formed and which is formed over the substrate where the silicon oxide layer is removed in the region where the thin film transistor is not formed. Also, planarization insulating films(28,32) which is formed on the moisture blocking insulating film, are provided between the lower electrode and the substrate.
