摘要

A polymer-stabilized blue phase liquid crystal display (BPLCD) with slanted wall-shaped electrodes is proposed.Compared with the traditional BPLCD with wall-shaped electrodes,the electrodes of the proposed BPLCD are slightly angled to obtain phase retardation in the entire cell even at the position of electrodes.The proposed BPLCD demonstrates a relatively higher average transmittance and overall brightness than the traditional BPLCD.Owing to the continuous improvement in image quality of liquid crystal displays (LCDs),they have been widely employed in desktop monitors,TVs,and mobile displays at present[1-5].With the development of LCDs the polymer-stabilized blue phase LCDs (BPLCDs)[6-11]can replace the conventional LCDs and become the nextgeneration display technology.The polymer-stabilized BPLCDs have numerous attractive features,such as submillisecond gray-to-gray response time,alignmentlayer-free process optically isotropic dark state and cell gap insensitivity[12-14].Because of these advantages,the fabrication processes of the BPLCDs are simplified,motion-image blurs are reduced,and color-sequential displays using RGB LEDs are enabled.
