Abstract
A method of manufacturing a display unit includes: forming, on a substrate, a thin-film transistor having an oxide semiconductor layer; and forming, above the thin-film transistor, a display region that includes a plurality of display elements. The oxide semiconductor layer is formed using a sputtering method in which a target and the substrate are opposed to each other. The target is made of an oxide semiconductor and includes a plurality of divided portions that are jointed in a planar form. A spacing interval between two joints that are formed by the plurality of divided portions and are side-by-side with one another of the target is equal to or less than a width of a luminance distribution arising in the display region in a direction substantially orthogonal to the joints.
