Abstract
A liquid crystal display for automatically adjusting brightness of interference image displayed at ECB sub pixels of quad type cells of a liquid crystal display panel in accordance with brightness of a background screen is disclosed. The liquid crystal display includes first to n-th look-up tables each holding a mapping of one first to n-th mappings of ECB brightness data to cell location information for the quad cells of the liquid crystal display panel; an image processor that calculates a brightness data distribution of an image; and a viewing angle controller that selects one of the first to the n-th look-up tables depending on the calculated brightness data distribution.
