Cutting wheel for glass substrate

摘要

A cutting wheel is provided for cutting a liquid crystal panel. The cutting wheel is disc shaped and includes a plurality of grooves disposed along an edge of the cutting wheel and cutting portions formed between the grooves. A pattern having a predetermined period is formed by multiple grooves and cutting portions. The grooves in each period have the same or different widths and depths and the cutting portions have probe shapes or cutting blades of different lengths. The cutting wheel is applied to dummy areas of the glass substrates forming the liquid crystal panel.
