Abstract
A liquid crystal display device comprising different liquid crystal aligning domains in each of a plurality of unit regions for improving a characteristic of a viewing angle. In at least one of the liquid crystal aligning domains, molecules of the liquid crystal near the first alignment layer are aligned in a first pretilt direction and at a first pretilt angle and molecules of the liquid crystal near the second alignment layer are aligned in a second pretilt direction generally opposite the first pretilt direction and at a second pretilt angle. The first pretilt angle is larger than the second pretilt angle so that molecules of the liquid crystal located intermediately between the first and second plates rise in accordance with the first pretilt angle when voltage is applied. This feature can be widely used in combination with a suitably selected arrangement of the other liquid crystal aligning domain for reducing rubbing steps and photolithography steps.
