Embodiment Construction

[0060] Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments but includes various modifications, substitutions, and improvements.

[0061] In the drawings, the dimensions of layers and regions may be exaggerated for clarity of illustration. The terms 'first', 'second', etc. can be used to explain various elements, but the elements are not limited to such terms. Terms are used to distinguish one element from another. Thus, an element referred to as a first element in one embodiment may be referred to as a second element in another embodiment. Unless the context requires otherwise, a singular expression may not exclude a plural expression.

[0062] In the following description, the term "comprises" or "comprises" is used to indicate features, numbers, steps, operations, elements, parts or combinations thereof without excluding other features, number...

Abstract

The invention provides a liquid crystal display. In the liquid crystal display, a first alignment layer formed on a first substrate includes a first region aligned in a first direction and a second region aligned in a second direction opposite to the first direction, and a second alignment layer formed on a second substrate facing the first substrate includes a third region aligned in a third direction different from the first direction and a fourth region aligned in a fourth direction opposite to the third direction. The liquid crystal molecules interposed between the first and second alignment layers are aligned in different directions in different domains defined by the first to fourth regions. A pixel electrode includes an extension part extending in at least one of the first to fourth directions. The aperture ratio and the light transmittance of the liquid crystal display are improved.

Description

technical field [0001] The present invention relates to liquid crystal displays. More specifically, the present invention relates to liquid crystal displays with improved display quality. Background technique [0002] Generally, a liquid crystal display (LCD) displays an image by applying a voltage to a liquid crystal layer that controls the transmittance of light passing through the liquid crystal layer. However, since light is transmitted along the alignment direction of liquid crystal molecules, LCDs may have a relatively narrow viewing angle compared to other display devices. [0003] In this regard, PVA LCDs (Vertical Alignment Configuration LCDs) and SPVA LCDs (Super Vertical Alignment Configuration LCDs) have been developed. In PVA LCDs and SPVA LCDs, each pixel is divided into domains and liquid crystal molecules are aligned in different directions in each domain. Vertically aligned liquid crystals are used in PVA LCDs and SPVA LCDs to form multi-domains in each p...
