PROBLEM TO BE SOLVED: To provide a production method of a laminate optical film, by which a laminate optical film having two optical films each having an optical axis can be produced with desired curling imparted, and a liquid crystal panel including the laminate optical film.SOLUTION: The production method of a laminate optical film in one embodiment aims to produce a laminate optical film by laminating a second optical film on a first optical film 10. The method includes: a curling adjustment step, in which a curling adjustment film 12 is laminated on the first optical film to obtain a first laminate film by use of a film lamination device 40 so as to mitigate curling of the first optical film by curling in a predetermined direction imparted by the lamination device; and a lamination step, in which the first laminate film and the second optical film are laminated by use of a film lamination device in such a manner that a first optical axis Sof the first optical film and a second optical axis of the second optical film form a predetermined angle, to obtain the laminate optical film as a second laminate film.SELECTED DRAWING: Figure 6 |
