Method of producing optical film laminates










Image Number 4 for United States Patent #8083886.

An object of the present invention is to simplify the production steps and achieve efficient use of optical film webs in a case of producing an optical film laminate having three or more layers of optical films laminated together. A method of producing optical film laminates by cutting a laminate into a desired shape includes: cutting a first optical film web into first cut pieces along first cut lines; laminating the first cut pieces onto a second optical film web to form a laminate film; cutting the laminate film into second cut pieces along second cut lines; and laminating the second cut pieces onto a third optical film web. An angle of the first cut lines is determined to have the first cut lines crossing the optical axis of the first optical film web at a predetermined angle, and an interval of the first cut lines is determined to have the width of the second optical film web substantially equal to the width of the first cut pieces. An angle of the second cut lines relative to the second optical film web is determined to have the second cut lines crossing the optical axis of the second optical film web at a predetermined angle, and an interval of the second cut lines is determined to have the width of the third optical film web substantially equal to the width of the second cut pieces.
