US 2006/0139748 A1 · Color electrophoretic display and method of manufacturing the same

Abstract

Provided are a color electrophoretic display and a method of manufacturing the same. The color electrophoretic display includes: a plurality of lower electrodes arranged on a lower layer and disposed with a predetermined interval therebetween; a plurality of first to third photoresist chambers arranged on the plurality of lower electrodes; first to third electronic inks accommodated in the plurality of first to third photoresist chambers respectively, and discriminatively operating to an electric field to independently display red, green, and blue colors; and a plurality of upper electrodes disposed with a predetermined interval therebetween and facing the plurality of lower electrodes with the plurality of first to third photoresist chambers being held therebetween.

A method of manufacturing an electrophoretic display, the method comprising the steps of:

(a) preparing an auxiliary substrate;
(b) adhering a first photoresist sheet onto the auxiliary substrate;
(c) exposing the first photoresist sheet using a first mask and forming a plurality of first photoresist chambers disposed with a constant interval therebetween and each having an opening;
(d) injecting a first electronic ink to the plurality of first photoresist chamber via the openings;
(e) adhering a second photoresist sheet onto the plurality of first photoresist chambers in which the first electronic ink is filled and covering the openings;
(f) changing an entire structure upside down and removing the auxiliary substrate;
(g) exposing the second photoresist sheet using a second mask and removing a part of the second photoresist sheet formed between the plurality of first photoresist chambers;
(h) repeating the steps (a) to (f) and preparing a plurality of second and third photoresist chambers disposed with a constant interval therebetween in which second and third electronic inks are filled, respectively;
and
(i) repeatedly and sequentially arranging the prepared plurality of first to third photoresist chambers and forming a first protective layer on one surface of each of the first to third photoresist chambers.
