It improves the temperature dependence of the threshold voltage without deteriorating various characteristics of the liquid crystal for a desired threshold voltage or time division driving, and has a stable high contrast over a wider temperature range, and a response speed in a room temperature and a low temperature region. The present invention provides an STN liquid crystal display device having a large display capacity and improved response to moving pictures, colors, and the like.n n n In a liquid crystal display device having a structure in which a liquid crystal is inserted into a pair of substrates and provided with at least an alignment control layer, a transparent electrode, and a polarizing plate, in the liquid crystal, general formulas (I) and (II).n n n n n n n n n n n n n Provided is a liquid crystal display device comprising one or two or more compounds selected from among them. |
