Abstract:
1. A method for manufacturing a color electrophoretic display device, comprising: 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, wherein the formation of the color filter layer includes: carrying out hydrophobic treatment of a surface of the electrophoretic layer; and spraying color droplets expressing a plurality of colors onto the surface of the electrophoretic layer, upon which the hydrophobic treatment is carried out, through a nozzle of an ink-jet printing device such that color droplets expressing one color are formed in one pixel region.
