Abstract:
A liquid crystal display panel includes in the following order: a first substrate including pixel electrodes; a first vertical alignment film; a liquid crystal layer containing liquid crystal molecules; a second vertical alignment film; and a second substrate including a counter electrode. The liquid crystal display panel includes pixels each including four alignment regions which provide different tilt azimuths to the liquid crystal molecules and are arranged in a longitudinal direction of each pixel. The liquid crystal display panel includes first, second, third, and fourth alignment regions providing the respective specific alignment azimuths. The liquid crystal molecules are aligned in a direction substantially perpendicular to the first and second vertical alignment films and at a tilt in the respective tilt azimuth directions with no voltage applied to the liquid crystal layer and are to be more tilted in the respective tilt azimuth directions upon application of voltage to the liquid crystal layer. The liquid crystal molecules are at a twist angle of substantially 0° in each of the four alignment regions.
