Abstract
Provided is a spacer microparticle spraying apparatus capable of selectively disposing spacer microparticles in electrode gaps where no pixels are present even on a substrate carrying an array of stripe electrodes in use for the STN liquid crystal display device, to a spacer particle spraying method and a method of manufacturing a liquid crystal display device which utilize said apparatus. The spacer microparticle spraying apparatus for selective disposition of a charged spacer microparticle on a substrate carrying a plurality of electrodes includes a spraying chamber adapted to accommodate the substrate, a spacer microparticle supply means for supplying the spacer microparticle into the spraying chamber and spraying it on the substrate, and a voltage application means for applying voltages to the electrodes disposed on the substrate, wherein the voltage application means is capable of applying different levels of voltages to the electrodes respectively.
