Abstract
There is disclosed a grinding apparatus for fabrication of a liquid crystal display device that is adaptive for improving the adsorption defect of a substrate onto a substrate stage. A grinding apparatus for fabrication of a liquid crystal display device disclosed in the present invention includes a plurality of substrate stage configured to make a linearly bi-directional movement; first and second grinding parts disposed in a series at an area to which the substrate stage moves; first to third aligning parts disposed at both ends of the first and second grinding parts and therebetween; and first and second cleaning parts disposed between the first and second grinding parts and the first and second aligning parts so as to clean the substrate stage.
Claims7
A grinding apparatus for fabrication of a liquid crystal display device comprising:
- a plurality of substrate stage configured to make a linearly bi-directional movement;
- first and second grinding parts disposed in a series at an area to which the substrate stage moves;
- first to third aligning parts disposed at both ends of the first and second grinding parts and therebetween;
- and
- first and second cleaning parts disposed between the first and second grinding parts and the first and second aligning parts so as to clean the substrate stage.
A method of grinding a liquid crystal display device comprising the steps of:
- moving first and second substrate stages to first and second aligning parts after performing the grinding process of the liquid crystal display panel as many times as pre-set;
- minimizing the size of the first and second substrate stages;
- cleaning the first and second substrate stages for the first time by using pure water DI;
- cleaning the first and second substrate stages by using air pressure;
- and
- carrying out the grinding process after changing the sizes of the first and second substrate stages, of which the cleaning is completed, to the size thereof when grinding.
