ABSTRACT:
An ink mixed with spacer members is ejected onto one or both of a TFT substrate and a CF substrate while an ink jet head having a plurality of ink jet nozzles is moved. The excursions of a predetermined number of ink jet nozzles from an end of the ink jet head overlap those of a next excursion of the ink jet head without causing overlapping of ejected ink within the overlapping area. An abrupt stepwise change in the amount of ejected ink is suppressed whereby an uneven gap is suppressed.
