A novel white‐emitting hybrid electroluminescent (EL) device based on an organic dye and an inorganic phosphor has been developed. In this device, the organic dye is excited by the luminescence energy of the inorganic phosphor, and exhibits white luminescence from the three primary colors. We developed the EL device using organic dyes that consist of coumarin 6 and a 4‐(dicyanomethylene)‐2‐i‐propyl‐6‐(1,1,7,7‐tetramethyljulolidyl‐9‐enyl)‐4H‐pyran (DCJTB)‐doped phosphor layer. Furthermore, a RGB color panel of the organic‐dye‐dispersed inorganic EL device with red luminescence of high color purity was produced.
