Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain such an optical film that sufficient performances for both of moisture resistance and optical function holding characteristics are obtd. even when the film is made large in size and that stable adhesion property is obtd. without causing warpage of a liquid crystal cell by applying an adhesive layer having each specified saturation water absorption and adhesion strength against peeling on one or both surfaces of an optical film material. SOLUTION: This optical film is produced by applying an adhesive layer 3 on one or both surfaces of an optical film material 2. This adhesive layer has
