(1) An electroluminescent material comprising an oxide having a perovskite type crystal structure and being represented by a general formula : RMO3 [wherein R represents a rare earth element, and M represents Al, Mn or Cr]; (2) an electroluminescent material comprising an oxide having a perovskite type crystal structure and being represented by a general formula : R2CuO4 [wherein R represents a rare earth element]; and (3) an electroluminescent material comprising an oxide having a perovskite type crystal structure and being represented by a general formula : RZ2Cu3O6 [wherein R represents a rare earth element, and Z represents an alkaline earth metal]. The above three electroluminescent materials emit a light of high brightness with less energy consumption, are reduced in the loss of a light due to the conversion to heat or the like, and are reduced in the deterioration due to the use for a long period of time, and they are characteristic in that they are inorganic electroluminescent materials which emit a light having a wavelength longer than that of a yellow light such as a blue or green light.
