摘要：
The method of dividing a glass substrate into separate pieces includes producing a crack along a dividing line on the substrate and acting on the crack with an aqueous cutting liquid during or immediately after producing the crack. The aqueous cutting liquid used in the method has a special composition that reduces the breaking forces applied to the glass substrate in order to divide it. The aqueous liquid contains an ionic organic compound, which has a cation with a positively charged nitrogen atom and a hydroxyl anion. Quaternary ammonium hydroxide compounds are especially preferred as the ionic organic compound.
