Abstract

PURPOSE: To obtain a visual field control planar body which is wide in a range of visual field control angles by laminating laminated light control films consisting of >=1 sheets of light control films having different characteristics on a transparent planar body. CONSTITUTION: The laminated light control films 23 formed by adhering the light control films 3a, 3b to each other with an adhesive film 2 are laminated between two sheets of transparent sheet glass 1 in the state of adhering the films by the adhesive film 2. The light control film 3a has the characteristics to selectively scatter only the incident light 11 within the angle range of 0 (direction 9) to 55 deg. (direction 10) from the direction perpendicular to the sheet glass 1 toward the base axis direction 8 of the visual field control thereof and to allow transmission of the incident light outside this range. The light control film 3b has the characteristics to selectively scatter only the incident light 12 within the angle range of 55 to 90 deg. from the direction 9 toward the base axis direction 8 of the visual field control thereof and to allow transmission of the incident light outside this range. Consequently, the visual field control planar body eventually has a visual field shielding angle range of 0 to 90 deg..
