Abstract
Discussed are a color electrophoretic display device with a color filter layer, which is formed in a droplet state on a rear surface of an electronic ink film through surface treatment so as to be capable of adjusting density of droplets in pixels and achieving correct alignment, and a method for manufacturing the same. The method includes forming a thin film transistor (TFT) array substrate including a display region, in which a plurality of pixel regions are defined in a matrix, and alignment keys provided at the outside of the display region, forming an electrophoretic layer including a micro capsule layer formed so as to correspond to the display region of the TFT array substrate, and forming a color filter layer on the electrophoretic layer using the alignment keys so as to correspond to the respective pixel regions of the display region.
