Abstract
A liquid crystal display (LCD) having an oblique electric field while a voltage is applied between the upper plate and the lower plate of the LCD is disclosed. The LCD includes a first regulating device of the upper plate and the second regulating device of the lower plate. As no voltage between the upper and lower plate, the liquid crystal molecules in the proximity of the first and the second regulating device are perpendicular to the upper and the lower plate. After a voltage is applied, an oblique electric field is produced by these regulating devices. The liquid crystal molecules are then rotated to parallel to the upper and lower plates because of the oblique electric field. The first and second regulating devices are bumps made of dielectric material or slits of electrodes.
