Abstract
A method of manufacturing an electro-optical device by cutting up a pair of mother substrates that are joined to each other by means of a sealant with an electro-optical material being sandwiched therebetween into a plurality of panel formation regions. The method includes: forming a groove along each of at least two pre-work cut lines in either one of the pair of mother substrates; blowing air on one edge face of a region between the grooves formed in the one of the pair of mother substrates; and removing the region between the grooves formed in the one of the pair of mother substrates by vacuuming the region. Herein, the vacuuming is applied to the other edge face of the region.
