Abstract
A method and apparatus for the manufacture of circuits for a large display device using stitch exposure. In the peripheral region of a circuit pattern on a mask, the method of stitch exposing provides for a joining of pairs of stitch regions in order to join in an interfitting state such that a smaller mask can be combined to form a larger display device. By causing the corresponding positional relationship of mask and plate to change in a direction in which a pair of stitch regions face each other, the arrangement of respectively formed pattern counterparts, after being placed in a mutually complementary interfitting relationship, are transferred so as to be joined to the respective stitch region of a circuit pattern region periphery already transferred onto the plate.
