Abstract: Liquid crystal，as a special state of matter between liquid and crystal，has extensive applications in
fields such as display technology due to its electro-optic effect．The experiment on the electro-optic effect of
liquid crystals is an important part of university physics experiments，which can help students deeply
understand the physical properties of liquid crystals and the mechanism of electro-optic conversion．This paper
takes TN-type liquid crystal as the research object，measures the electro-optic data of liquid crystal
corresponding to the different positions of the analyzer，and obtains the changes of threshold voltage，saturation
voltage，contrast and slope with the position of the analyzer by drawing the electro-optic curve．It provides a
practical reference for the teaching and research of liquid crystal-related knowledge and is conducive to
cultivating students＇ scientific inquiry ability．
