Abstract
A fabrication method for a liquid crystal display. A pair of substrates is provided. An alignment layer is formed on the respective substrates. An energy beam is irradiated on a predetermined area of at least one of the alignment layers. The alignment layer is rubbed to form a first pretilt-angle area in the predetermined area exposed to the energy beam, and a second pretilt-angle area not exposed to the energy beam. The pair of substrates are bonded with a preset gap therebetween, and a liquid crystal layer is inserted between the substrates. The liquid crystals corresponding to the first pretilt angle area have a first pretilt angle of θ1, while those corresponding to the second pretilt angle area have a second pretilt angle of θ2.
