1. A method of manufacturing an electrophoretic display sheet, comprising:
- applying a mixture of a plurality of microcapsules and a binder on a substrate, the substrate having a first contact angle θ
1 between a reference liquid, each of the microcapsules having a second contact angle θ
2 between the reference liquid, the binder having a third contact angle θ
3 between the reference liquid, the θ
1, the θ
2, and the θ
3 having a relationship of θ

Abstract
A method of manufacturing an electrophoretic display sheet that includes: applying a mixture of a plurality of microcapsules and a binder on a substrate, the substrate having a first contact angle θ1 between a reference liquid, each of the microcapsules having a second contact angle θ2 between the reference liquid, the binder having a third contact angle θ3 between the reference liquid, the θ1, the θ2, and the θ3 having a relationship of θ3>θ2>θ1; and evaporating the mixture to form an electrophoretic layer on the substrate, the electrophoretic layer including the plurality of the microcapsules.
