Abstract
An electrophoretic display (EPD) shows a high contrast and a color display. The EPD blocks a channel of a thin film transistor from an incident light in order to prevent a current leakage. The color display may also include a white, black, red, green, blue, yellow, cyan, magenta or other color pigment in a micro-capsule.
