ABSTRACT:
A thin film EL element comprises a substrate, an electrode formed on the substrate, a ZnO insulation layer which is formed on the electrode and which has crystalline orientability, a light emitting layer formed on the ZnO insulation layer having crystallinity, and a second electrode formed on the light emitting layer. The ZnO insulation layer having crystalline orientability, is formed as a sublayer for the light emitting layer, and is made of a material having its c-axis oriented perpendicular to the substrate.
