PURPOSE: A liquid crystalline film is provided to improve the luminous efficiency of a display device. CONSTITUTION: A liquid crystal film includes a base material layer(101), a first liquid crystal layer(102), and a cholesteric liquid crystal layer(103). A first liquid crystal layer is formed on one surface of the base material layer. The cholesteric liquid crystal layer is formed in the other surface of the base material layer. The cholesteric liquid crystal layer includes at least two cholesteric aligned liquid crystal areas. |
