摘要

PROBLEM TO BE SOLVED: To provide a process for producing a printing plate for spacer formation which is capable of forming spacers of shapes to lessen the occurrence of the disturbance and failure of the display images of a liquid crystal panel by accompanying the pressing, etc., of a touch panel and a printing plate for spacer formation, liquid crystal display device as well as the touch panel. ;SOLUTION: Irradiation light 32a from a light source 32 is exposed to a photosensitive resin plate 30 via a film 31 formed with masking patterns corresponding to the spacers to be formed. The irradiation light 32a is formed as parallel light beams. The irradiation angle of the parallel light beams of the light source 32 is changed by relatively moving the light source 32 and the film 31 and the sectional region of the photosensitive resin plate 30 is exposed with the irradiation light 32a via the film 31. The photosensitive resin plate 30 is subjected to photoresist processing, by which trapezoidal openings 30a are etched at the photosensitive resin plate 30. The photosensitive resin plate 30 is used as the printing plate for spacer formation or the female die for forming the printing plate for spacer formation, by which the trapezoidal spacers for the liquid crystal panel or the spacers for touch panels are formed.;COPYRIGHT: (C)2001,JPO
