GLASS SUBSTRATE FOR A DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A production method of a glass substrate for a display device is provided to produce the glass substrate having high intensity with low costs by cutting at a non-reinforced cut thin film pattern using a wheel and using a chemically reinforced glass thin film. CONSTITUTION: A glass substrate for a display device includes a glass thin film (101) and a cut thin film pattern (102a). The glass thin film has a first chemically reinforced unit on the upper surface, a non-reinforced unit on the edge of the upper surface, and a second chemically reinforced unit on the lower surface. The cut thin film pattern is formed on the non-reinforced unit, and has a thickness of 1,000-10,000 angstroms. A production method of the glass substrate comprises the following steps: forming a cut thin film on a mother glass substrate; forming the cut thin film pattern for the ion exchange process suppression on a scribe line of the mother glass substrate; forming the first chemically reinforced unit, the non-reinforced unit, and the second chemically reinforced unit on the mother glass substrate; and cutting the upper side of the cut thin film pattern for cutting the non-reinforced unit.
