Embodiment Construction

[0022] It will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it can be directly on, connected to, or coupled to the other element or layer or can be There are intervening elements or layers. In contrast, when an element is referred to as being "directly on," "directly connected to" or "directly coupled to" another element or layer, there are no intervening elements or layers present. Like numbers refer to like elements throughout the drawings. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. In particular, relative terms such as "under", "below", "under", "over" and "above" may be used herein to easily describe an element or characteristic relative to The interrelationship of another element or feature in a drawing.

[0023] Referring to FIG. 1, a dual field switching mode liquid crystal display 310 includes a first display ...

Abstract

In a display apparatus, a first display substrate includes a common electrode to which a common voltage is applied. A second display substrate facing the first display substrate includes a first pixel electrode and a second pixel electrode. The first and second pixel electrodes formed in one pixel region are spaced apart from and insulated from each other. A first data voltage having a first polarity with reference to the common voltage is applied to the first pixel electrode, and a second data voltage having a second polarity different from the first polarity with reference to the common voltage is applied to the second pixel electrode. Thus, a fringe field is formed between the first and second display substrates and a lateral field is formed in the second display substrate, thereby improving a transmittance and a response speed of the display apparatus.

Description

technical field [0001] The invention relates to a display device, in particular to a liquid crystal display. Background technique [0002] Generally, a liquid crystal display includes an array substrate, a color filter substrate, and a liquid crystal layer. The color filter substrate includes a common electrode applied with a common voltage, and the array substrate includes pixel electrodes applied with a pixel voltage having a voltage level different from that of the common voltage. Accordingly, a fringe field is formed between the array substrate and the color substrate due to a voltage difference between the common voltage and the pixel voltage, thereby rotating liquid crystal molecules of the liquid crystal layer. [0003] The liquid crystal molecules have a rotation rate that varies depending on the strength of a fringe field formed between the array substrate and the color filter substrate. That is, when the strength of the fringe field increases, the rotation rate o...
