A method for manufacturing an electro-optic device having a panel structure including an electro-optic material disposed between a pair of substrates, a spacer disposed between the pair of substrates to define the gap therebetween, and a color filter provided on one of the pair of substrates includes forming a substrate region to be used as the panel structure and a peripheral region to be separated from the substrate region on each of a pair of pre-substrates, bonding the pair of pre-substrates together to form a pre-panel structure, and dividing the pre-panel structure to form the panel structure, wherein a stacked structure including the spacer and a colored layer constituting the color filter or a protective film covering the color filter is disposed in the peripheral region of the pre-panel structure.
