ABSTRACT:
The prevent invention is a method in which microcapsules are placed at desired locations selectively accurately and easily to produce a high accuracy electrophoretic display panel. In the production method of a display panel of the present invention, the microcapsules (43) are uniformly coated onto a substrate (41), on which electrodes (42) is formed by using an optical hardening resin as a binder material (44). Next, the binder material (44) is hardened by selectively irradiating a light beam to the only locations desired for placing the microcapsules (43) by using a photomask (45). The binder material (44) of portions not hardened is removed by washing in water. Thus, the microcapsules can be selectively and accurately placed at the only desired positions. A color electrophoretic display panel, in which each microcapsule of three primary colors is placed in a predetermined arrangement, can be produced by sequentially performing the processes for the three types of microcapsules corresponding to three primary colors.
