    摘要： In an EL device (10) in which a blue light emitting material obtained by doping Ce as a luminescent center into CaGa X S Y host material is used for a luminescent layer (5), values of X and Y in the CaGa X S Y host material are set in ranges of 1.4≦X≦1.9, 2.9≦Y≦3.8. The blue light emitting material thus obtained has a new structure defined by the fact that an X-ray diffraction spectrum obtained by using Cu Kα radiation as a X-ray source has at least one peak in diffraction angles of 13.5±0.2 degree, 14.6±0.2 degree and 25.7±0.2 degree. The blue light emitting EL device (10) has a luminance higher than that of a conventional EL device.
