Liquid crystal display and fabrication method thereof

A method for fabricating a liquid crystal display, comprising:

• providing a first substrate;
• providing a second substrate disposed opposite to the first substrate;
• forming a light absorptive electrode layer on the second substrate facing the first substrate;
• providing a liquid crystal host;
• adding a pair of chiral, dopants having different optical activities into the liquid crystal host to form at least two kinds of cholesteric liquid crystal materials, wherein each chiral dopant of the pair of the chiral dopants has the same chemical structure;
• and
• disposing the at least two kinds of cholesteric liquid crystal materials between the first substrate and the second substrate to form at least two layers of cholesteric liquid crystal layers.

A liquid crystal display, comprising:

• a first substrate;
• a second substrate disposed opposite to the first substrate;
• a light absorptive electrode layer disposed on the second substrate facing the first substrate;
• a first cholesteric liquid crystal layer disposed between the first substrate and the second substrate, wherein the first cholesteric liquid crystal layer comprises a first chiral dopant;
• a second cholesteric liquid crystal layer disposed between the first substrate and the second substrate, wherein the second cholesteric liquid crystal layer comprises a second chiral dopant;
• and
• wherein the first chiral dopant and the second chiral dopant have different optical activities, wherein the first chiral dopant and the second chiral dopant have the same chemical structure, wherein the first cholesteric liquid crystal layer and the second cholesteric liquid crystal layer are a left-handed cholesteric liquid crystal layer and a right-handed cholesteric liquid crystal layer, respectively, wherein the first chiral dopant is a left-handed chiral dopant having a molecular stereostructure represented by Formula (III):
• wherein R is C1-6 alkyl, and
• wherein the second chiral dopant is a right-handed chiral dopant having a molecular stereostructure represented by Formula (II):
• wherein R is C1-6 alkyl.
