Abstract

The present invention can improve the uniformity of film thickness after drying. Its solution is, comprises: with respect to the drawing area (21) of the area smaller than desired drawing area on the glass substrate (30), the step of jetting alignment film ink from inkjet head; With respect to drawing area (21) ) around the surrounding drawing area (22), the step of ejecting the alignment film ink from the inkjet head; and relative to the surrounding drawing area (23) around the surrounding drawing area (22), ejecting the alignment film from the inkjet head The step of ink, thereby, can reduce the swelling of the alignment film ink after drying in the peripheral drawing area (23) of the peripheral portion.

Description

technical field [0001] The present invention relates to an alignment film forming apparatus, an alignment film forming method, a drawing apparatus and a drawing method, and particularly relates to an alignment film forming apparatus, an alignment film forming method, a drawing apparatus and a drawing method which can improve the uniformity of the film thickness after drying. Background technique [0002] Conventionally, an inkjet-type drawing apparatus has an inkjet head provided with a plurality of nozzles in the sub-scanning direction, and is an apparatus in which the inkjet head is moved in the main-scanning direction by a carriage mechanism to perform drawing. [0003] In addition, the drawing device can be widely used in the production of color filters used in color liquid crystal devices or color electroluminescence (EL) display devices, not only for printing characters, drawings, and photographs (see Patent Document 1). [0004] In an ink jet drawing apparatus, ink is...
