Abstract: Provided are a composition for a light transmittance control film, and a light transmittance control film. According to the inventive concept, the light transmittance control film includes a matrix part including a copolymer and a polymer chain which is grafted to the copolymer; and a dispersed part including a polymer derived from a first monomer, and are provided in the matrix part, wherein the polymer chain is derived from the first monomer, first light transmittance is shown while external force is applied, and second light transmittance which is greater than the first light transmittance may be shown after the external force is removed.
