Claim Text:
1. A light emitting device manufacturing method comprising: mask arrangement of arranging a mask that includes a first opening and one or more second openings that are spaced apart from each other along a plane of the mask, the one or more second openings being arranged adjacent to the first opening along a longitudinal direction of the first opening, on a substrate; first pattern formation of, after the mask arrangement, forming a pattern on the substrate with a first light emitting material that emits light of a first spectrum, through the first opening and the one or more second openings of the mask; first mask movement of, after the first pattern formation, moving the mask in the longitudinal direction of the first opening by a distance that is less than a width of the first opening in the longitudinal direction of the first opening and greater than or equal to a width of the one or more second openings in the longitudinal direction of the first opening; and second pattern formation of, after the first mask movement, forming a pattern on the substrate with a second light emitting material that emits light of a second spectrum that differs from the first spectrum, through the first opening and the one or more second openings of the mask.
