ORGANIC THIN-FILM EL DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a high-fineness organic thin-film EL device which forms and separates electrode lines at a pitch as fine as hundred microns by using a pattern mask on a substrate in a vacuum vapor deposition method. SOLUTION: This organic thin-film EL device has the electrode lines formed by superposing partly of plural electrodes 15a and 15a on each other. The apertures of the pattern mask for forming the electrode lines are formed of a structure taking bending and distortion into consideration. One electrode line is formed by plural times of vapor deposition by moving the pattern mask described above.
