Embodiment Construction

[0042] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.

[0043] It will be understood that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

Abstract

The present invention provides a display substrate and liquid crystal display having the same. The liquid crystal display includes: a first pixel connected to first and second gate lines, a first positive data line and a first negative data line, and which is supplied with a positive data voltage from the first positive data line when enabled by a first gate-on voltage from the first gate line, and is supplied with a negative data voltage from the first negative data line when enabled by a second gate-on voltage from the second gate line; and a second pixel connected to the first and second gate lines, a second positive data line and a second negative data line, and which is supplied with a negative data voltage from the second negative data line when enabled by the first gate-on voltage and is supplied with a positive data voltage from the second positive data line when enabled by the second gate-on voltage.

Description

technical field [0001] The present invention relates to a display substrate and a liquid crystal display having the display substrate, and more particularly, to a display substrate with reduced power consumption and a liquid crystal display having the display substrate. Background technique [0002] A liquid crystal display includes a first substrate having a plurality of pixel electrodes, a second substrate having a common electrode, a liquid crystal layer having dielectric anisotropy between the first substrate and the second substrate, a gate driving a plurality of gate lines driver and a data driver that outputs data signals. [0003] In order to prevent degradation of the liquid crystal layer, the liquid crystal display utilizes a polarity inversion driving method. For example, various polarity inversion driving methods include frame inversion driving, row inversion driving, column inversion driving, and dot inversion driving. In the frame inversion driving method, po...
