PURPOSE: A liquid crystal display is provided to make low-voltage driving compatible with high display quality in an active-driving type, IPS-system liquid crystal display using a liquid crystal having a negative dielectric anisotropy. CONSTITUTION: This liquid crystal display(50) comprises a pair of glass substrates(1,14), a liquid crystal(9), a common electrode(2) and a pixel electrode(5) formed on the substrate(1) so as to generate, under applied voltage, an electric field(25) having a component parallel to the substrate surface together with a signal electrode(6) and a TFT, alignment films(8,10) formed on the substrates(1,14), and a polarizing plate(15), In the liquid crystal display(50), the liquid crystal(9) contains liquid crystal molecules having dicyanobenzene structures and a negative dielectric anisotropy, Thus, a low-voltage driving is made possible while voltage retention is maintained in a tolerable range wherein the display quality of a liquid crystal display is not degraded. |
