Abstract

A process for producing an optical display panel by laminating an optical laminated sheet to an optical display element without fouling or marring the optical laminated sheet. A process for producing an optical laminated sheet is also provided which comprises: a step in which continuous optical sheets (1 and 3; and 11 and 13) are drawn out respectively of rolls (2 and 4; and 12 and 14); a first laminating step in which the optical sheets drawn are laminated to form a continuous optical laminated sheet; a second laminating step in which the optical laminated sheet is laminated as it is to an optical display element (7); and a cutting step in which the optical laminated sheet is cut. In the cutting step, the optical laminated sheet is cut into a size having an area which is larger than that of the display region of the optical display element and is smaller than that of the optical display element itself. The second laminating step may follow the cutting step.
