[0006] However, due to the introduction of such an angle, the opening size of each pixel area of ​​the LCD may be reduced; since the resolution of the LCD is improved by reducing the size of all pixel areas, the data lines and In the case where the gate line is extended in a straight line and a switching element (TFT) is provided in a corner of such a pixel unit cell structure, by thus forming an angle between the cutout and the vertical standard line, the liquid crystal Corresponding aperture transmittance factor degradation of the display

Embodiment Construction

[0032] The present disclosure will be provided more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments are shown. As those skilled in the art would realize, having a understanding of the present disclosure, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present teachings.

[0033] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Throughout the specification, like reference numerals refer to like elements. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.

[0034] Next, a liquid crystal display according to an exemplar...

Abstract

A liquid crystal display includes a first substrate (110), a gate line (121) disposed on the first substrate and extending parallel to a major horizontal reference line (X) of the display, and a plurality of pixel unit cells disposed on and tesslating a display area of the first substrate where each unit cell includes a first field generating electrode (191) and a second field generating electrode (270) with an insulating layer (180z) interposed therebetween, wherein a first one of the first and second field generating electrodes has a plurality of cutouts (92) defined therein for producing corresponding liquid crystal domains, the plurality of cutouts each including a first inclined edge portion forming a first angle ( 1) with the vertical reference line (Y) and a second inclined edge portion forming a second angle ( 2) with the vertical reference line (Y) that is different from the first angle, wherein the ratio of the length of the first inclined edge portion to the length of the cutout is about 80% or more but less than 100%, and the density of the plurality of pixels is about 200 PPI or more.

Description

technical field [0001] The present disclosure relates to a liquid crystal display, and more particularly, to a liquid crystal display having improved transmittance and reduced display quality degradation. Background technique [0002] A liquid crystal display (LCD) is one of the most widely used types of flat panel displays today. In general, an LCD is a display device used to adjust the amount of transmitted light by applying a voltage between electrodes so that the liquid crystal molecules of the liquid crystal layer rearrange and thereby impart desired optical properties to the transmitted light. Effects (for example, adjusted polarity). [0003] The advantage of LCDs is that they are as easy to form as stripes or another matrix as repeating groups of sub-pixels of different colors, but the disadvantage of LCDs is that the side visibility of the image is lower than the front visibility. Therefore, various methods of arranging and driving liquid crystals to have differen...
