ABSTRACT:
A thin film electro-luminescence composition comprising an alkaline earth metal thiogallate represented by the following compositional formula: ##EQU1## wherein M.sup.1 is Sr or Ba; RE is a lanthanoid element; a and b are integers which are different from each other; and wherein x is 0.001 to 0.1 with the proviso that ##EQU2## is excluded or comprising an alkaline earth metal thioaluminate represented by the following compositional formula: ##EQU3## wherein M.sup.2 is Ca, Sr or Ba; RE is a lanthanoid element; c and d are integers which may be different from each other; and wherein y is 0.001 to 0.1,
and a thin film electro-luminescence device comprising said thin film electro-luminescence composition as a luminescence layer.
