Abstract

A plate-like workpiece having a transparent, glass, glass-like, ceramic and/or crystalline layer, such as for use in an electronic display screen, is processed into separate segments by first incompletely severing the workpiece along outer contours of bounded segments, by forming holes through the layer with a laser beam, leaving the segments interconnected at narrow connections, and then separating the segments by severing the web-like connections.
