Abstract
According to an aspect, a manufacturing method of a display device includes: obtaining a first reference position on a surface of a holding substrate based on positions of a plurality of first alignment marks of the holding substrate; and aligning the holding substrate with a transfer destination substrate such that the first reference position on the holding substrate and a second reference position on a surface of the transfer destination substrate coincide. The holding substrate is sectioned into a plurality of first sections and a plurality of second sections when viewed from one direction. Each of the first sections is provided in a part of a gap between the second sections when viewed from the one direction, has a light transmission rate higher than a light transmission rate of the second sections, and forms the first alignment mark through which light passes when viewed from the one direction.
