ORGANIC LIGHT EMITTING DIODE DISPLAY AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: An organic light emitting display device and a manufacturing method thereof are provided to polish the edge of a cross-sectional surface of a display substrate using a grinder, thereby eliminating a crack of the edge generated by cutting the display substrate. CONSTITUTION: A mother panel is formed by welding a second substrate on a first substrate. A panel(20) is separated by cutting the mother panel along a boundary of a cell of the mother panel. The panel is inserted into a grinder(10) which revolves by including a polishing part which has a polishing surface and a shaft connected to the polishing part. An edge of the panel is polished by touching a single edge of a cut surface of the first substrate to the polishing surface of the grinder.
