Abstract:
1. A liquid crystal display comprising: a liquid crystal panel in which at least one of a pixel electrode and a common electrode within a pixel generates a lateral electric field in a first direction perpendicular to a longitudinal direction of the at least one electrode, the electric field rotating liquid crystals to control an image; and a backlight on a back of the liquid crystal panel, wherein the backlight has an output angle range that varies depending on directions of light radiated onto the liquid crystal panel, wherein the at least one electrode comprises repeating electrode structures extending in the first direction, wherein the liquid crystal panel is arranged so that light scattered from the repeating electrode structures that occurs due to an incident light from the first direction intensifies by interfering with the incident light and so that light scattered from the repeating electrode structures that occurs due to incident light from a direction perpendicular to the first direction does not intensify, or dims relative to that due to incident light from the first direction, by interfering with the incident light, and wherein an incident angle range of light incident to the liquid crystal panel from the first direction is relatively narrower than an incident angle range of light incident to the liquid crystal panel from a direction perpendicular to the first direction.
