Abstract
The invention relates to electronic paper and hand-writing electronic paper device. The electronic paper comprises two substrates and an electro-optic display material layer, wherein the electro-optic display material layer is arranged between the substrates and at least one of the substrates is an anisotropic conductive base material layer. The substrates of the electronic paper and hand-writing electronic paper device adopt the anisotropic conductive base material layers, voltage is applied to the anisotropic conductive base material layers, electric fields are vertically or obliquely applied to the electro-optic display material layer at a specific position. Due to the fact that the anisotropic conductive base material layers are conductive, voltage drop on the substrates is low, the voltage is basically applied to the electro-optic display material layer to allow the same to display a specific optical state. Due to anisotropic conduction of the base material layers, horizontal insulation or resistance is large, horizontal electric field diffusion is small, display state of the nearby electro-optical materials is unaffected, every two adjacent electrodes do not interfere each other, and exquisite images can be displayed.
