Abstract

Embodiments are disclosed for a liquid crystal display and writing device that has a high brightness and a high contrast ratio. The device includes a first two conductive layers and a liquid crystal film between the conductive layers. The liquid crystal film includes a first liquid crystal layer, a second liquid crystal layer and a middle polymer layer between the first and second liquid crystal layers. The first and second liquid crystal layers are configured to switch from a light scattering state to a light reflective state to display content. The first and second liquid crystal layers are further configured to switch from the light reflective state to the light scattering state to erase the content.
