| 摘要 |
The invention relates to a liquid crystal display device having electrodes which form a picture element matrix and generate an electric field substantially parallel to the substrate; it is characterized in that it has a brightness recovering time of not greater than 5 min, the brightness recovering time being the time until the brightness of a displayed portion that has been displayed for 30 min and is turned off, returns to the background brightness. The products ( epsilon r rho )LC, ( epsilon r rho )AF and/or ( epsilon r rho )PAS of the specific dielectric constant epsilon r and the specific resistivity rho of the liquid crystal layer (LC), the orienting film (AF) and/or the insulating film (PAS) are preferably within the range of 1 x 10<9> to 8 x 10<1><5> OMEGA .cm. <IMAGE> <IMAGE>
