This application claims the priority and the benefit under 35 U.S.C. §119(a) on Korean Patent Application No. 10-2011-0100127 filed on Sep. 30, 2011 and Korean Patent Application No. 10-2012-0059550, the entire contents of which are hereby incorporated by reference.
1. Field of the Invention
The present disclosure relates to a liquid crystal display apparatus, and more particularly, to a liquid crystal display apparatus capable of improving uniformity in luminance of RGB pixels by asymmetrically designing RGB pixels, and enhancing display quality.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principle of the invention. In the drawings:
FIG. 1 illustrates a pixel structure of an LCD apparatus according to the related art;
FIG. 2 illustrates a pixel design changed to decrease luminance deviation by each color;
Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
On explanation about the embodiments of the present invention, if it is mentioned that a first structure is positioned ‘on or above’ or ‘under or below’ a second structure, it should be understood that the first and structures are brought into contact with each other, or a third structure is interposed between the first and second structures. Herein, the ‘structure’ may be, for example, an electrode, a line, a wiring layer, or a contact.
Before a detailed explanation with reference to the accompanying drawings, various modes of the LCD apparatus are shown briefly. Based on a method for controlling alignment of liquid crystal layer, the LCD apparatus may be classified into Twisted Nematic (TN) mode, Vertical Alignment (VA) mode, In-Plane Switching (IPS) mode, Fringe Field Switching (FFS) mode, and etc.
