Unevenness due to dispersion of properties among organic electroluminescent devices is prevented to form an optimal light emission form for exposure. The organic EL devices in lines R1, R2 and R3 have respectively different x-coordinates and move relatively in a y-axis direction with respect to a photosensitive material at a time of exposure to form a horizontal scan line R-all by the exposure. Similarly, lines R4, R5 and R6 further form the horizontal scan line R-all. Thus, the horizontal scan line R-all is exposed twice: by the lines R1, R2 and R3, and by the lines R4, R5 and R6.
