Abstract
Provided is a light control film capable of gradually changing the in-plane transmittance and thereby adding an in-plane gradation between light and dark. A light control filmaccording to the present invention includes: a first electrodeA and a second electrodeB disposed facing each other; a light control materialdisposed between the first electrodeA and the second electrodeB and changing the transmittance in accordance with the potential difference between the first electrodeA and the second electrodeB; and a potential gradient forming part for providing the gradient of the potential difference in the extension direction of the first electrodeA and the second electrodeB.
