The present invention provides a method for producing a liquid crystal film that can obtain an ultra-thin optical film and solve the problems of heat shock test resistance and delamination during rework, which have been problems in the past. A liquid crystal material layer formed on an alignment substrate and having a fixed liquid crystal alignment is adhered to a re-peelable substrate via an adhesive, and then the alignment substrate is peeled to re-apply the liquid crystal material layer. After transferring to the peelable substrate, the laminated body composed of the removable substrate / adhesive layer 1 / liquid crystal substance layer / adhesive layer 2 / temporary substrate is obtained by adhering to the temporary substrate via the adhesive 2 1st process, 2nd process which peels a releasable board | substrate from the said laminated body, Then, it is made to peel between liquid crystal material layer / adhesive layer 2, and the liquid crystal film which consists of adhesive layer 1 / liquid crystal material layer is obtained 3rd A method for producing a liquid crystal film, which is obtained through at least each of the steps.
