PROBLEM TO BE SOLVED: To solve the problems that a light emitting material is scratched due to the touch of the light emitting material adhering to a basic body with a mask and precise matching of a mask and the cathode is difficult. SOLUTION: After the light emitting material having a plurality of colors adheres by a second mask through a first mask arranged so as to adhere to the basic body closely, the second mask is removed, and a pattern of a back face electrode adheres by the first mask. Since the second mask used to adhere a plurality of times by moving does not come into direct touch with the organic light emitting material, a scratch does not occur, mask matching becomes easy, a back face electrode mask by the first mask is fixed to dispense with new mask matching, and a process becomes simple.
