ABSTRACT:
A liquid crystal display (LCD) and a fabrication method thereof are provided. The LCD includes a first substrate and a second substrate opposite to the first substrate. At least two layers of cholesteric liquid crystal layers are disposed between the first and the second substrates, wherein chiral dopants with different optical activities are respectively added in the cholesteric liquid crystal layers, and the chiral dopants have the same chemical structure. The fabrication method includes providing a first substrate and a second substrate opposite to the first substrate. A plurality of chiral dopants with different optical activities and having the same chemical structure are mixed into the same liquid crystal host respectively to form at least two kinds of cholesteric liquid crystal materials. Then, the cholesteric liquid crystal materials are disposed between the first and the second substrates to form at least two layers of cholesteric liquid crystal layers.
