Abstract: PURPOSE: A method of fabricating a liquid crystal display is provided, which forms a multi-domain using light so as to realize wide viewing angle. CONSTITUTION: Twisted nematic liquid crystal and chiral dopant are mixed with each other in a predetermined ratio to be inserted into pixels(18). A mask is selectively formed on the pixels. Then, the pixels are exposed. Accordingly, a liquid crystal display constructed in a manner that liquid crystal is filled between upper and lower substrates(4) including an alignment film(10) aligned within the pixels. The chiral dopant includes single-molecule chiral dopant that reacts on light to be changed into polymer, and low-molecule chiral dopant that does not react on light. The mask has a symmetrical triangular or inverse-triangular shape to divide the pixel into four.
