METHOD OF POLISHING GLASS FOR OLED AND GLASS FOR OLED MANUFACTURED USING THE SAME

The present invention relates to a method polishing glass for OLED and glass substrate for OLED manufactured with the same. A glass polishing device is employed for polishing. The glass polishing device includes a lower plate having its top surface attached with a polishing pad for being rotated toward a predetermined direction; an upper plate closely contacted the lower plate for being rotated thereon to the left and right according to a predetermined angle; and a polishing liquid supply device for supplying polishing liquid to the lower plate. The polishing method includes the steps of: using polishing liquid containing cerium oxide based polish to perform the first polishing to the glass substrate; and using polishing liquid containing silicon oxide based polish to perform a second polishing to the glass substrate processed by the first polishing. Accordingly, it is able to provide a method polishing glass for OLED capable of increasing the flatness and luminance of the glass substrate, and a glass substrate manufactured with the method for OLED.
