===Advanced super view (ASV){{anchor|ASV}}===
Advanced super view, also called ''axially symmetric vertical alignment'' was developed by [[Sharp Corporation|Sharp]].<ref>{{cite web|url=https://www.sharpsma.com/advanced-super-view-asv-|title=Sharp Advanced Super View (ASV) - Sharp|website=www.sharpsma.com|access-date=2019-06-12}}</ref>  It is a VA mode where liquid crystal molecules orient perpendicular to the substrates in the off state. The bottom sub-pixel has continuously covered electrodes, while the upper one has a smaller area electrode in the center of the subpixel.

When the field is on, the liquid crystal molecules start to tilt towards the center of the sub-pixels because of the electric field; as a result, a continuous pinwheel alignment (CPA) is formed; the azimuthal angle rotates 360 degrees continuously resulting in an excellent viewing angle. The ASV mode is also called CPA mode.<ref>[http://www.personal.kent.edu/%7Emgu/LCD/asv.htm The World of Liquid Crystal Displays] from personal.kent.edu/%7Emgu</ref>
