Abstract
PURPOSE: To enable accurate dimensions and shapes to be obtained without any waste of materials and with good workability by providing the specific grooves in the cutting positions on the opposite face sides of glass substrates and cutting and separating the glass substrates by utilizing these grooves.
CONSTITUTION: Grooves 23 of U-form in section having the relation of the formula (t is the thickness of glass substrate mm; d is the depth of grooves mm) are provided along the cutting lines at boundaries of upper substrate parts 2 and lower substrate parts 7 to a glass substrate 1 alternately disposed with the substrate parts 2, 7 and formed respectively with transparent electrodes and common electrodes. The glass substrate 101 similarly alternately disposed with lower substrate parts 109 and upper substrate parts 104 and provided with grooves 117 and the substrate 1 are opposed and are thermally bonded by means of adhesive agents 27, 129. Next, scores 23, 127 are given to the opposite surfaces of the grooves 13, 117. thereafter pressure is applied like the arrows B, C to the outside surfaces of the substrates 1, 101 opposing to the grooves 117, 13, then they crack between the groove 13 and score 23 as well as between the groove 117 and score 127, whereby they are separated.
