Abstract
A liquid crystal display which includes a pair of substrates, a liquid crystal layer sandwiched between the pair of substrates, and electrodes respectively formed on facing surfaces of the pair of substrates for applying an electric field to each pixel. A first alignment film is formed on the surface of one of the pair of substrates and covers the electrodes formed thereon. The first alignment film aligns the liquid crystal molecules in the liquid crystal layer in a direction generally vertical to a plane of the substrates. A second alignment film is formed on the surface of the other of the pair of substrates and covers the electrodes formed thereon. The second alignment film aligns the liquid crystal molecules in a direction generally parallel to the plane of the substrates and gives a pre-tilt to the liquid crystal molecules. An area corresponding to each pixel on the second alignment film is divided into a plurality of domains each having a single easy direction, and at least two domains in the pixel area have different easy directions. In addition, the easy directions of the two domains are different by 180 degrees, and the liquid crystal display also includes a pair of polari…
