Abstract
Abstract PCT No. PCT/JP89/01181 Sec. 371 Date Jul. 18, 1990 Sec. 102(e) Date Jul. 18, 1990 PCT Filed Nov. 21, 1989 PCT Pub. No. WO90/05998 PCT Pub. Date May 31, 1990.This invention relates to an injection type thin film luminescence element having a high luminance and a high stability characterized in having two electrode layers at least one of which is transparent or translucent and having between these two electrode layers a luminescence function-manifesting layer comprising a laminated layer of a p-type or n-type inorganic semiconductor thin film layer and an organic compound thin film layer.
