The film formation mask has a plurality of openings according to the film pattern, and false openings formed outside the area containing the openings but not useful in forming organic layer for forming luminescent areas. False openings are formed in positions corresponding to the outside of display area, and forms false patterns of an organic layer on the inner side of the adhesive area.
