Abstract
A light control film includes two transparent electroconductive resin substrates each having a transparent electroconductive film and a transparent resin substrate; and a light control layer sandwiched between the transparent electroconductive film sides of the two transparent electroconductive resin substrates. The transparent electroconductive film of one transparent electroconductive resin substrate having a primer layer is cut through a cutting line to have a shape of a picture or character, and the cutting line is in a form that a start point for the cutting and an end point for the cutting make a closed region. The closed region of the picture of character is electrically insulated from the transparent electroconductive film around the shape of the picture or character. The light control film enables to improve adhesiveness between film matrix and substrates and to provide stable control function.
