Title:
CONTINUOUS ROLL OF OPTICAL FUNCTION FILM, METHOD OF MANUFACTURE OF LIQUID CRYSTAL DISPLAY ELEMENT EMPLOYING SAME, AND OPTICAL FUNCTION FILM LAMINATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/026327
Kind Code:
A1
Abstract:
An objective of the present invention is to alleviate striped display distortion that occurs in liquid crystal display elements when taking optical function film from a continuous optical function film roll having cutting lines in the width direction thereof and laminating the optical function film on a liquid crystal panel. This continuous roll has an optical function film layered body (15) in a continuous web shape rolled thereupon, said layered body (15) including at least an optical function film (10) and a carrier film (13) that is detachably layered on the optical function film. The optical film (10) is cut into a plurality of optical function film sheets by cut lines (16) being formed along the width direction of the optical film layered body (15). It is possible to resolve the problem by making the resilience to bending per unit of length of the optical function film in the length direction fall within a prescribed range.
