Abstract
Disclosed is an electrophoretic display (EPD) device capable of delaying or preventing a sealant from leaking down by forming a dam pattern prior to a sealing process using the sealant, and a method for fabricating the same. The EPD device comprises: gate lines and data lines crossing each other to define a pixel region, and formed on a lower substrate; a thin film transistor (TFT) electrically connected to the gate lines and the data lines; a passivation film covering the TFT; a pixel electrode electrically connected to the TFT; a display layer formed on the pixel electrode and the passivation film, and having an electrophoretic substance; a common electrode formed on an entire surface of the display layer; an upper substrate formed on the common electrode; a seal pattern formed on each outer circumferential surface of the lower substrate, the upper substrate, and the display layer; and a dam pattern formed on the lower substrate adjacent to the seal pattern.
