Abstract

An electrophoretic display device includes a lower substrate having pixel electrodes thereon to define a plurality of pixel areas; partition walls formed on the lower substrate to surround the pixel electrodes; electrophoretic dispersion liquid having a plurality of charged particles colored to display colors, the electrophoretic dispersion liquid filled into the plurality of the pixel areas defined by pixel electrodes and surrounding the partition walls; a membrane layer disposed on the partition walls and covering the electrophoretic dispersion liquid, the membrane layer comprising a plurality of hole patterns at portions corresponding to the plurality of the pixel areas; and an upper substrate bonded with the lower substrate such that the membrane layer is disposed therebetween.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2010-0099865 filed on October 13, 2010, which is hereby incorporated by reference as if fully disclosed herein. technical field [0002] The present invention relates to an electrophoretic display device, and more particularly, to an electrophoretic display device that improves driving stability and display quality, and improves production efficiency, and a method for manufacturing the electrophoretic display device. Background technique [0003] In general, an electrophoretic display device refers to a device capable of displaying images using electrophoresis in which charged particles to be dyed move due to an electric field applied from the outside. Here, "electrophoresis" means a phenomenon in which charged particles move in an electrophoretic dispersion (electrophoretic ink) due to Coulomb force when an electric field is applied to the electrophoretic dispersion in which the charged particles a...
