PROBLEM TO BE SOLVED: To provide a preparation method of an EL panel wherein a plate making is unnecessary. SOLUTION: This is the preparation method wherein the first and the second comb-shaped electrodes 20A, 20B are installed in parallel on a surface of printed- circuit board 13 and wherein a dielectric layer 15 is formed on the printed-circuit board 13 and covers these first and second comb-shaped electrodes 20A, 20B and wherein a luminous layer 16 is formed on this dielectric layer 15, and the dielectric layer 15 and the luminous layer 16 are formed by heat transcription.
