Abstract
A new type multicolor electroluminescent EL device with a thin-film/powder phosphor emitting layer has been fabricated without vacuum process. High-luminance multicolor emissions were obtained in EL devices using a ZnGa_2O_4 : Mn, ZnS : Mn or BaMgAl_<14>O_<23> : Eu powder phosphor in combination with a ZnGa_2O_4 : Mn thin-film phosphor : 335 cd/m^2 in green, 964 cd/m^2 in orange and 2.7 cd/m^2 in blue, respectively, when driven at 1kHz.
