Abstract
A granular liquid crystal of uniform grain diameter is discharged from a liquid crystal application unit. A charged plate ionizes the discharged granular liquid crystal. A power source supplies a plus voltage to the charged plate via a switch which turns on or off a supplied voltage from the power source. If the switch is turned on, the granular liquid crystal is ionized, and the ionized granular liquid crystal is deflected by a deflecting plate to reach a substrate. On the other hand, if the switch is turned off, the granular liquid crystal is not ionized, and not deflected by the deflecting plate to be captured by a garter. The switch is turned on or off in synchronism with the frequency of the piezoelectric transducer, whereby a desired amount of liquid crystal can be dripped on the substrate.
