Patent ID: 8480832

Claim:
A method of producing an optical film laminate having three or more optical films laminated together, each of the optical films having an optical orientation axis, the method comprising: a first film layer forming step comprising cutting a first optical film having an elongated shape into first optical film pieces along cutting lines crossing a longitudinal direction of the first optical film; and disposing the first optical film pieces adjacent to each other in a substantially band or strip shape, thereby forming a first film layer having an optical orientation axis crossing a longitudinal direction of the band or strip-shaped first optical film pieces; a second film layer forming step comprising cutting a second optical film having an elongated shape into second optical film pieces along cutting lines crossing a longitudinal direction of the second optical film; and disposing the second optical film pieces adjacent to each other in a substantially band or strip shape, thereby forming a second film layer having an optical orientation axis crossing the longitudinal direction of the band or strip-shaped second optical film pieces; and forming an optical film laminate by holding a third optical film layer, the first film layer and the second film layer in a laminated state, and cutting the films held in the laminated state to produce the optical film laminate, wherein the first film layer forming step is performed by feeding out the third optical film from a raw film roll in the longitudinal direction and placing the first optical film pieces directly on the fed third optical film; and the second film layer forming step is performed by placing the second optical film pieces directly on any one of the fed third optical film and the formed first film layer.
