摘要： Each pixel has a reflection region to produce a display in reflection mode. The first substrate includes: a pixel electrode for each pixel; and a first vertical alignment film. The second substrate includes: an opposite electrode opposite the pixel electrodes; and a second vertical alignment film. Of the first and second vertical alignment films, only the second vertical alignment film exerts an alignment-regulating force that determines a pretilt angle. Each pixel electrode includes a plurality of subpixel electrodes. The opposite electrode has an opening in an area corresponding to one of four corners of at least one of the plurality of subpixel electrodes. Liquid crystal molecules in a thickness-wise middle portion of the liquid crystal layer on the subpixel electrode are oriented toward the opening.

摘要： In a liquid crystal display device, liquid crystal molecules are oriented in a vertical direction to the first substrate and the second substrate by the first molecule orientation film and the second molecule orientation film, respectively, in a non-driving state. A structural pattern is formed so as to extend in a first direction parallel a surface of the liquid crystal layer and so as to form, in a driving state, an electric field periodically changing in a second direction that is parallel to the liquid crystal layer and vertical to the first direction. The liquid crystal molecules substantially tilt in the first direction in the driving state.

摘要： In a liquid crystal display device (100), each pixel row group is selected by a common scan signal voltage, each pixel row group including N pixel rows which adjoin one another in a column direction. Where two pixel rows which adjoin each other in a column direction and which are included in different pixel row groups are a first pixel row and a second pixel row, the first pixel row includes a pixel which has a pixel electrode (16) capacitively coupled with a gate bus line (12) which is associated with the second pixel row. When the first pixel row is included in the qth group, the second pixel row is included in the (q+1)th group. A scan signal voltage supplied to gate bus lines which are associated with the (q+1)th group switches from low to high before a scan signal voltage supplied to gate bus lines which are associated with the qth group switches from high to low.
