摘要:
In the liquid crystal display device (100A) of the present invention, the pixel electrode (121) has a notch (122a2) provided for a portion of a line. If the azimuthal component of liquid crystal molecules (182), located approximately at the middle of the thickness of a liquid crystal layer (180) in an area where the respective alignment regions of first and second alignment films (130) and (170) overlap with each other to a viewer's eye, is called a “reference alignment azimuth”, an oblique electric field, generated by a counter electrode (160) and the notch (122a2) of the pixel electrode (121) upon the application of a voltage, causes the azimuthal component of the liquid crystal molecules (182) in a region of the liquid crystal layer (180) associated with at least a portion of the notch (122a2) of the pixel electrode (121), to intersect with the reference alignment azimuth at an angle of 90 degrees or less.
