| Summary: | 碩士 === 國立彰化師範大學 === 光電科技研究所 === 101 === In this thesis, the electro-optical properties of silica nanoparticle-doped (SN) liquid crystal (LC) and polymer-stabilized blue phase liquid crystal (PSBPLC) devices are investigated. The addition of monomer expands the existing temperature range and reduces the hysteresis width of the blue phase liquid crystal (BPLC). However, the formed polymer networks decrease the platelet size of the BPLC. The platelet size is independent on the temperature cooling rate, and the response time of the PSBPLC is slightly slow. The addition of SNs also expands the existing temperature range and reduces the hysteresis width of the BPLC. However, the platelet size becomes larger with the slower temperature cooling rate. The platelet size of the SN-doped BPLC is larger than that of the pure BPLC, and the response time of the SN-doped BPLC can be reduced less than 1 ms.
