(54) Title: METHOD AND APPARATUS FOR SEPARATING GLASS SHEETS 110 90 FIG. 1 (57) : Methods and apparatus for separating a glass sheet are described. An apparatus and a method utilize a vent bar having a cushion that exerts a force on the glass sheet adjacent a vent line to break the glass into two pieces at the vent line. The edge of the glass sheet has excellent perpendicularity without subsequent grinding and/or polishing so that the glass sheet can be used as a light guide plate in a display.
