Abstract
Stacked mother substrates are efficiently separated into individual display device substrate-units by a scribing and breaking method. In a state in which the transported stacked mother substrates PN are held in a raised state, scribe lines SBL, SBLare formed on a first substrate SUBand a second substrate SUBat the same position. Then, first of all, the stacked mother substrates are broken into strip-like substrates by breaking a periphery and removing a peripheral wastage and, thereafter, the strip-like substrates are broken into display device substrate-units PNL and, thereafter, internal wastages of the respective display device substrate-units PN are separated and removed.
