Abstract
This invention has its object to provide a method of liquid display device production which enables spacer disposition in interelectrode spaces not having electrode, namely at black matrix sites, in STN type and TFT type liquid crystal display devices and further enables even spacer disposition to attain a uniform cell thickness all over the substrate to thereby produce liquid crystal display devices of high contrast and high display uniformity stably and in good yields, with a reduced spray step tact time, as well as liquid crystal display devices produced by such method.This invention provides a method for producing a liquid crystal display devicecomprising spraying spacers onto at least one of a first substrate comprising at least pattern-forming transparent electrodes and a second substrate to be disposed opposingly above the first substrate and filling a liquid crystal into the space between both the substrates,and comprising, in spraying positively or negatively charged spacers onto the substrate, disposing the substrate in close contact with an earthed conductive stage having a volume resistance of not more than 1010 &OHgr;cm and applying, to the transparent electrodes, a vo…
