Abstract
The present invention provides a manufacturing method of a flat-panel display unit and a carrier therefor which make it unnecessary to implement alignment in each step, except for alignment which require higher precision, by performing the alignment in advance in the pre-stage of a series of steps. The present invention also provides a manufacturing method of a flat-panel display unit which allows alignment with accuracy of about 50 to 100 .mu.m to be performed simply, reliably and quickly. According to the inventive manufacturing method, a display panel is mounted non-shiftably on the carrier and while being mounted thereon, is then carried between processing machines and is processed by the processing machines. In mounting the display panel on the carrier, it is aligned with the carrier in advance by visually aligning alignment marks thereof. In processing it by the processing machine, the carrier and the processing machine are put into a predetermined state in which they are aligned and thereby, the display panel is put into a state in which it is aligned with the processing machine.
