Abstract
The liquid crystal film cell of the present application can control expansion of a base film at a high temperature by applying an expansion control layer having a high-temperature expansion coefficient different from that of the base film thereto, thereby effectively maintaining a cell gap at a high temperature, whereby high-temperature durability can be improved and gravity defects can be eliminated.
