Patent number: 12386224Abstract: A cholesteric liquid crystal polarizing grating includes two substrates, two alignment layers, and a liquid crystal layer. An interlayer space is formed between the two substrates. The two alignment layers are respectively located on inner surfaces of the two substrates facing the interlayer space. Alignment directions of the alignment layers are periodically arranged. An alignment plane of each alignment layer is divided into a plurality of rows. The alignment directions in a same row are the same, and the alignment directions in adjacent rows rotate relative to each other. The plurality of rows with the alignment directions rotated by 180 degrees defines a grating period. The liquid crystal layer is located in the interlayer space. Liquid crystal molecules adjacent to the two alignment layers are arranged following the alignment direction of each alignment layer to form a polarizing grating with the grating period.Type: GrantFiled: August 14, 2024Date of Patent: August 12, 2025Assignee: NATIONAL SUN YAT-SEN UNIVERSITYInventors: Chun-Ta Wang, Tsung-Hsien Lin, Yu-Chieh Li, Cheng-Kuan Wu, Cheng-Chang Li, Li-Min Chang, Duan-Yi Guo, Kuan-Wu Lin
