Abstract: A stretchable transparency-adjusting film includes an inner elastic part having a three-dimensional network shape and including a first elastomer, an inorganic thin film surrounding the inner elastic part, and an outer elastic part surrounding the inorganic thin film and including a second elastomer. A scattering unit defined by the inner elastic part, the inorganic thin film and the outer elastic part in a cross-section is orientated in an inclined direction to a vertical direction and a horizontal direction.
