OPTICAL FUNCTIONAL FILM CONTINUOUS ROLL, METHOD FOR MANUFACTURING LIQUID CRYSTAL DISPLAY ELEMENT USING THE SAME, AND OPTICAL FUNCTIONAL FILM PASTING DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress the occurrence of striped display unevenness in a liquid crystal display element when a film is unreeled from a continuous roll having cutting lines in a width direction of an optical functional film, and the optical functional film and a liquid crystal panel are pasted together.;SOLUTION: A continuous roll of the present invention is formed by reeling a continuous web shape optical film laminate 15, which includes at least an optical functional film 10 and a carrier film 13 laminated on the optical functional film in a freely peelable manner, in a roll shape. By forming cutting lines 16 along a width direction of the optical film laminate 15 in the optical functional film 10, the optical functional film 10 is cut into multiple optical functional film sheet pieces. Flexural rigidity per unit length in a longitudinal direction of the optical functional film is set within a predetermined range.;COPYRIGHT: (C)2012,JPO&INPIT
