Abstract
An ink-jet printing apparatus that uniformly coats an alignment layer of an LCD device is provided. The ink-jet printing apparatus includes a head where the head has a head body and a supply pipe disposed inside the head body. The supply pipe allows the passage of a material through the head. The head also includes a nozzle and a foam removing means. The nozzle is in fluid communication with a portion of the supply pipe which discharges the material. The foam removing means is disposed in the nozzle and dissipates foam in the material.
