Abstract
An active matrix type liquid crystal display composed of a liquid crystal cell is described. In the liquid crystal cell , liquid crystals at the upper and lower interfaces of a liquid crystal layer inserted between an array substrate having pixel electrodes and an opposed substrate having an opposed electrode have pretilt angles opposite to each other in a positive/negative sense and are aligned in parallel with each other, forming a spray alignment. This liquid crystal display performs displaying by bend-aligning such a liquid crystal cell . The pixel electrodes are formed on a flattening film for covering switching elements or wiring electrodes flat. With this arrangement, a spray to bend alignment transition can be reliably, easily caused in a short time within the liquid crystal cell pixels, so that an OCB mode liquid crystal display free from alignment defects and having high picture quality can be achieved.
