Abstract:
1. A display element manufacturing method of a display element manufacturing, apparatus comprising: a transporting step which transports a flexible sheet substrate, where a plurality of fiducial marks are formed in a longitudinal direction at a predetermined interval, at a predetermined speed in the longitudinal direction with a rotating transport roller while causing the flexible sheet substrate to be in close contact with a surface of the transport roller over a predetermined angle; a detecting step which detects the fiducial marks with a first alignment system and a second alignment system of which visual fields are set in two locations respectively, the two locations being within a region where the flexible sheet substrate is in close contact with the transport roller and being separated from each other in the longitudinal direction at a predetermined distance; a calculating step which calculates an expansion or contraction of the flexible sheet substrate in the longitudinal direction based on detection results of the first alignment system and the second alignment system; and a processing step which performs a process for forming the display element in a predetermined region on the flexible sheet substrate with a processing apparatus based on the calculated expansion or contraction and positions of the fiducial marks.
