Writable device

Abstract

A writable device is provided. The writable device includes a first substrate, a second substrate, a liquid-crystal layer, a first alignment layer and a second alignment layer. The second substrate is opposite to the first substrate. The liquid-crystal layer is disposed between the first substrate and the second substrate. The first alignment layer is disposed between the first substrate and the liquid-crystal layer. The second alignment layer is disposed between the second substrate and the liquid-crystal layer. The first alignment layer and the second alignment layer are vertically oriented. In its initial state, the liquid-crystal layer is in a transparent state. In the writing state, the liquid-crystal layer corresponding to the pressed writing area is in a scattering state. In its clear state, at least a part of the liquid-crystal layer corresponding to the pressed writing area is in the transparent state.
