Method for manufacturing flat display device

Provided is an electrophoretic display device and a method of manufacturing and repairing the electrophoretic display device. The electrophoretic display device includes: a gate line, a gate electrode, and a common electrode, separated a predetermined distance from the gate line, which are formed on a substrate; a gate insulation layer formed on an overall surface of the substrate including the gate line; a data line configured to define a pixel area by crossing the gate line; a source electrode configured to extend from the data line; a drain electrode separated from a predetermined distance from the source electrode; a protection layer formed on an overall surface of the substrate including the data line, the source electrode, and the drain electrode; a pixel electrode formed on the protection layer and connected to the drain electrode; an electrophoretic film formed on the substrate including the pixel electrode; a common line formed on a boundary portion between the pixel areas and configured to connect the common electrodes formed in the respective pixel areas; and a repair hole formed by removing the protection layer corresponding to the common line to expose the gate insulation layer.
