Abstract
To provide a continuous web of optical film laminate provided with static electrification prevention function which allows for promptly attenuating static charge of optical film sheet and carrier film electrified by peeling action in RTP lamination method and apparatus. The problem has been solved with a continuous web of optical film laminate for using in RTP lamination method and apparatus, in which static electrification prevention function is provided to optical film sheets and a carrier film configuring the continuous web of optical film laminate, such that sheet resistance of each of the optical film sheets and the carrier film is 1012 Ω/sq or less so as to promptly attenuate static charge of the carrier film to be collected, which is statically electrified by peeling action, and the optical film sheets to be laminated to panel components, which are also statically electrified by peeling action.
