Abstract

A liquid crystal display of the invention includes a plurality of pixels each of which has a liquid crystal layer and a plurality of electrodes for applying a voltage to the liquid crystal layer and which are arranged in a matrix of rows and columns, wherein: each of the plurality of pixels has a first sub-pixel and a second sub-pixel which can apply mutually different voltages to the liquid crystal layer, where the first sub-pixel has a higher brightness than the second sub-pixel in certain gradations; the first sub-pixel and the second sub-pixel each has: a liquid crystal capacitor formed by a counter electrode and a sub-pixel electrode opposing the counter electrode via the liquid crystal layer, and a storage capacitor formed by a storage capacitor electrode connected electrically to the sub-pixel electrode, an insulating layer, and a storage capacitor counter electrode opposing the storage capacitor electrode via the insulating layer; the counter electrode is a single electrode shared by the first sub-pixel and the second sub-pixel, and the storage capacitor counter electrodes of the first sub-pixel and the second sub-pixel are electrically independent of each other; and the storage capacitor counter electrode of the first sub-pixel in any of the plurality of pixels and the storage capacitor counter electrode of the second sub-pixel of a pixel adjacent to any of the pixelsin the column direction are electrically independent of each other.

Description

[0001] This application is a divisional application with an application date of December 3, 2004, an application number of 200410099783X, and an application named "Liquid Crystal Display". technical field [0002] The present invention relates to a structure and / or driving method capable of reducing viewing angle dependence of gamma characteristics in a liquid crystal display. Background technique [0003] A liquid crystal display is a flat panel display with favorable characteristics including high resolution, small thickness, light weight, and low power consumption. Its market share is also expanding rapidly with the improvement of display performance and yield, and its price advantage compared with other types of displays. [0004] Generally, the conventionally used twisted nematic (TN) liquid crystal display has liquid crystal molecules with positive dielectric anisotropy. between the upper and lower bases. When a voltage is applied to the liquid crystal layer, the liq...
