PROBLEM TO BE SOLVED: To solve a problem that, since light-emitting elements of blue and green colors are inferior to that of a red color in brightness and luminous efficiency in a light-emitting layer of organic light-emitting elements, quality and reliability of display is problematic in the case these three primary colors are synthesized to use them as a display medium displaying in color. SOLUTION: In the light-emitting layer 90 constituted of red color elements 92R, blue color elements 92B, and green color elements 92G, a vibration of a given frequency 170 is added on an interface jointing with at least either color element 92 out of the blue color elements 92B and the green color elements 92G to make a surface of the interface rugged.
