A method for fabricating a blue phase liquid crystal display is provided. A first substrate is arranged opposite to a second substrate, in which the first and second substrates include a first and a second electrode, respectively. A blue phase liquid crystal layer is sealed between the first substrate and the second substrate, in which the blue phase liquid crystal layer includes a positive blue phase liquid crystal and a monomer. A voltage is applied to the first electrode and the second electrode such that a vertical electric field is formed. The blue phase liquid crystal layer is illuminated with a light source such that the monomer performs polymerization to produce a polymer-stabilized positive blue phase liquid crystal. A blue phase liquid crystal display is also disclosed herein.
