Abstract

PURPOSE: To obtain mixed light definitely without mutual interference with a light- emitting center, by forming a light-emitting layer constituting an element of several lamination layers in different color regions.
CONSTITUTION: On heat-proof glass substrate 1 of Pyrex glass, transparent electrode 2 of In2O3, SnO3, etc., is formed, on which the 1st dielectric layer 3 formed of a composite film of SiO3 and Si3N4 is bonded. On it, the 1st light-emitting layer 4a of ZnS:Mn and the 2nd light-emitting layer 4b of ZnS:Tb are provided by stacking, Al back electrode 6 is fitted via the 2nd dielectric layer 5 of Si3N4, whose terminal is led out, and a terminal is fitted to electrode 2 as well. In this constitution, the density of Mn is fixed between 0.1 and 2.0 weight %, and that of TbF3 is between 0.1 and 4.0 mole %. As a result, light emitting centers are excited in mutually independent areas, definite mixed color can be obtained without mutual interference, and density quenching never occurs.
