Abstract
A liquid crystal display device according to the present invention includes a vertical alignment type liquid crystal layer 32. Each pixel electrode thereof 12 has a plurality of unit electrode portions 12a, each of which has a conductive film and slits 13 that have been cut through the conductive film. When a predetermined voltage is applied between the pixel electrode and a counter electrode, a liquid crystal domain is produced in association with each unit electrode portion and liquid crystal molecules in the liquid crystal domain come to have a substantially radially tilting alignment state. As a result, the device of the present invention achieves a wide viewing angle and a fast response characteristic.
