Abstract:
Provided is an optical film laminate wherein pressure-sensitive adhesive layers are not exposed to the outside. In a method for manufacturing said optical film laminate, the widths of a second film (32) and third film (33) which are laminated onto a first film (31) are both made smaller than the width of the first film (31), and the second film (32) and third film (33) are sequentially laminated onto the first film (31) such that neither protrudes past the first film (31) in the width direction. Thus, pressure-sensitive adhesive layers (32A and 33A) in the optical film laminate (30) are not exposed to the outside.
