The invention is directed to a method for forming a flexible electro-optic film. The method comprises steps of providing a first substrate having a conductive layer formed thereon and then forming a first locating structure over the conductive layer, wherein the locating structure includes target regions and periphery regions. The surface tension of the target regions is difference from that of the periphery regions. Thereafter, an electro-optic medium placing process for forming an electro-optic droplet on each of the target regions is performed. A solidifying process for forming a capsule wall covering the electro-optic droplet on each of the target regions is performed. The first substrate is laminated with a second substrate.
