A novel method is proposed to measure twist angle and optical retardation of liquid crystal display in this paper. The new method which is one of single-wavelength methods has three characteristics  introducing a method of measuring the total intensity ratio of the transmitted light to eliminate the influence of absorption by the polarizer  using circularly and homogeneously aligned LC cell (CH-LC) as a unique polarization-converting device  analyzer  using variable sector diaphragm and photodetector to detect the total intensity of transmitted light whose original polarization direction is continuously changed from 0 to arbitrary angle  CH-LC  liquid crystal display and so on. The twist angle () and optical retardation (nd) can be derived by using Jones matrix analysis and a curve fitting where and nd are fitting parameters. Experiment proved the results are accurate  the process of operation is fast  the devices are economical.
