Patent ID: 7903321

Claim:
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.
