Abstract
Disclosed is a liquid crystal display having an improved characteristic of viewing angle by modifying a pixel electrode and a common electrode construction respectively. In a liquid crystal display, upper and lower substrates are opposed to each other and spaced from each other by a predetermined distance. A liquid crystal layer is interposed between the upper and the lower substrates. A pixel electrode is formed at a portion of an inner surface of the lower substrate corresponding to a pixel area, and the pixel electrode has an uneven surface including first convex portions and first concave portions. A common electrode is formed at a portion of an inner surface of the upper substrate corresponding to the pixel electrode, so as to form an electric field together with the pixel electrode. The common electrode has an uneven surface including second convex portions and second concave portions.
