ABSTRACT:
Disclosed is a device for grinding a liquid crystal display panel improving the efficiency of using equipment by independently operating first and second grinding units for grinding the unit liquid crystal display panel. The present invention includes a first grinding unit grinding edges of short or long sides of the unit liquid crystal display panel in a normal mode and a second grinding unit grinding the edges of the short or long sides of the unit liquid crystal display panel that are not ground by the first grinding unit in the normal mode or grinding the edges of the long and short sides of the unit liquid crystal display panel in an emergency mode.
