Patent number: 10877319Abstract: Disclosed is a liquid crystal display device comprising an array substrate and an opposite substrate arranged facing the array substrate, wherein the structure of said array substrate comprises elongated and evenly spaced slit electrodes and electrode gaps between the slit electrodes, and said opposite substrate comprises a bulk electrode; and further comprises a liquid crystal composition between said array substrate and the opposite substrate. The liquid crystal display device has a higher light transmittance, such that more backlight passes through the liquid crystal display device, resulting in the liquid crystal display device having a higher luminance.Type: GrantFiled: August 22, 2018Date of Patent: December 29, 2020Assignee: SHIJIAZHUANG CHENGZHI YONGHUA DISPLAY MATERIAL CO., LTD.Inventors: Xuefeng Li, Kelun Shu, Kai Xu, Lihong Gui, Qian Zhang, Zhengqiang Li, Yunxia Qiao, Qing Cui, Wenxiao Xing
