Abstract
In a liquid crystal display apparatus including first and second substrates having a liquid crystal layer therebetween, a plurality of pixel electrodes formed over the first substrate, and a counter electrode formed on the second substrate, the liquid crystal layer is divided into a plurality of regions having different orientation of liquid crystal for one of the pixel electrodes, and openings are provided in the pixel electrodes in alignment with discontinuity of orientation of liquid crystal formed by the different orientation of liquid crystal. Also, a plurality of conductive light shield layers are provided in alignment with the openings. Further, a bias voltage is applied to the conductive light shield layers.
