摘要:
A vertical-alignment liquid crystal display device includes: one substrate on which plural pixel electrodes and thin film transistors (TFTs) corresponding to the pixels, scanning signal lines for supplying gate electrodes of these TFTs with a gate signal, and data signals lines for supplying drain electrodes of the TFTs with data signals are provided; an opposing substrate on which an opposing electrode opposed to the pixel electrodes is provided; vertical-alignment films covering surfaces of the respective substrates where electrodes are formed; and a liquid crystal layer sealed between these substrates and having a negative dielectric constant. On the inner surface of the one substrate, auxiliary electrodes to generate electric fields of a predetermined value between the auxiliary electrodes and the opposing electrode provided on the inner surface of the other substrate are provided respectively corresponding to those portions around the plural pixel electrodes that are close to at least the TFTs.
