Abstract
A electrophoretic display device manufacturing method includes bonding a substrate including a pixel electrode and a stacked film including a transparent electrode layer and an electrophoretic display layer, and forming a color filter layer having a pixel pattern corresponding to a pattern of the pixel electrode above a base material surface of the stacked film. The substrate has a region where the electrophoretic display layer is not arranged when the substrate and the stacked film are bonded, a pixel alignment pattern is drawn in the region, and in the forming the color filter layer, the color filter layer is formed while performing alignment using the pixel alignment pattern.
