ABSTRACT:
The present invention is a method for spreading spacing particles on a surface of a substrate used to form a liquid crystal display panel. The method comprises the steps of relatively moving the substrate and a spreading nozzle with respect to one another as the spreading nozzle spread the spacing particles such that the spacing particles spread from the spreading nozzle trace a predetermined trace on the surface of the substrate. Electric charge on the substrate is discharged while relatively moving the substrate and the spreading nozzle such that the spreading nozzle spreads the spacing particles on a discharged portion of the surface of the substrate.
