Abstract: A substrate-cutting stage includes a main stage and a dummy stage spaced apart from each other with a cutting region interposed therebetween and that support a substrate. The main stage supports a first portion of the substrate, the dummy stage supports a second portion of the substrate, and the cutting region overlaps a to-be-cut portion of the substrate disposed between the first and second portions.
