Abstract
PURPOSE:To make a visual angle direction symmetrical in front of the panel, by getting rid of a shift of the visual angle direction caused by driving voltage between threshold level voltage and saturation value voltage, by means of shifting the orientation of a liquid crystal is advance. CONSTITUTION:As for the visual angle range of a gradation display panel of a TN type liquid crystal display panel, the best visual angle direction in case (m) of 1.5 times critical voltage Vc is shifted by 45 deg. against the best visual angle direction in case (l) of 3 times Vc. Accordingly, rubbing direction 30, 40 of each electrode plate of both the scanning side and the signal are shifted in advance so as to be a prescribed visual angle direction in the working voltage range. The rubbing axis is rotated to the right by 45 deg.. In case of its visual angle range, the visual angle direction in case of low voltage becomes a prescribed direction.
