METHOD PRINTING ALIGNMENT LAYER OF LIQUID CRYSTAL DISPLAY AND PRINTING APPARATUS OF ALIGNMENT LAYER USED THEREIN

摘要

A method for printing an alignment layer of an LCD and an alignment layer print apparatus used for the same are provided to check, remove and recover non-discharge of alignment liquid caused by bubbles formed in a head and a nozzle, thereby reducing faults by the non-discharge of the alignment liquid. A alignment layer printing method of an LCD(Liquid Crystal Display) comprises the following steps of: mounting a mother board assembly on a stage(S211); aligning a head having a nozzle for discharging alignment liquid in one side of the stage; checking whether the alignment liquid is discharged from the nozzle by driving the head for a predetermined time(S213); and circulating the alignment liquid within the head if the alignment liquid is not discharged from at least a part of the nozzle(S217).
