Abstract

PURPOSE:To inhibit electric discharge by a liquid crystal layer of an image signal voltage written in each picture element without using an accumulation capacity, by specifying the resistivity of a liquid crystal. CONSTITUTION:It is prevented that impurities are mixed into a liquid crystal and a specific resistance is set to >=10<11>OMEGA.cm. That is, when a liquid crystal resistance is >=10<11>OMEGA.cm, the holding characteristic becomes satisfactory without providing an accumulation capacity. Especially, the variance of a threshold voltage Vthec of a liquid crystal defined by a signal amplitude value of 50% transmissivity can be suppressed to <=0.4V (60Hz driving), therefore, a liquid crystal display device being free from a display defect such as a black stain, uneven black, etc., can be realized. Also, when the liquid crystal resistance is set to >=3X10<11>OMEGA.cm, the variance of Vthec can be suppressed to 1/2<=0.2V, and the liquid crystal display device having a higher picture quality is obtained.
