Abstract: A liquid crystal display device is provided. The liquid crystal display device includes a first substrate having a pixel unit, wherein the pixel unit has a pixel electrode. A second substrate is disposed opposite to the first substrate, having an opposite electrode. A first polarizer is disposed under the first substrate. A second polarizer is disposed under the second substrate, wherein a polarization axis of the second polarizer is vertical to that of the first polarizer. A liquid crystal layer with chiral dopants having negative dispersion characteristics is disposed between the first and second substrates.

Abstract: A driving method of a blue phase liquid crystal (BPLC) display apparatus cooperated with a BPLC display apparatus having at least one data line, at least one scan line and at least one pixel comprises the steps of: transmitting a first gray level voltage to the pixel through the data line; transmitting a first recovery voltage to the pixel through the data line; and transmitting a first black frame insertion voltage to the pixel through the data line, wherein the absolute value of the first recovery voltage is higher than those of the first gray level voltage and the first black frame insertion voltage. The invention can diminish the dark-state leakage of the BPLC display apparatus.
