This application claims priority under 35 U.S.C. 119 to Korean Patent Application No. 10-2009-0013611, filed on Feb. 18, 2009, which is hereby incorporated by reference in its entirety.
1. Field of the Disclosure
This disclosure relates to a photo mask and a method of manufacturing a liquid crystal display device of an in-plane-switching (IPS) mode using the same.
The accompanying drawings, which are included to provide a further understanding of the embodiments 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 disclosure. In the drawings:
FIG. 1 is a perspective view showing an IPS mode LCD panel of the related art;
FIG. 2 is a planar view explaining the driving characteristic of liquid crystal molecules in the LCD panel shown in FIG. 1;
Reference will now be made in detail to the preferable embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. These embodiments introduced hereinafter are provided as examples in order to convey their spirits to the ordinary skilled person in the art. Therefore, these embodiments might be embodied in a different shape, so are not limited to these embodiments described here. Also, the size and thickness of the device might be expressed to be exaggerated for the sake of convenience in the drawings. Wherever possible, the same reference numbers will be used throughout this disclosure including the drawings to refer to the same or like parts.
First, a photo mask according to an embodiment of the present disclosure will be described.
FIG. 4A is a planar view illustrating a photo mask according to an embodiment of the present disclosure, and FIG. 4B is an enlarged planar view showing a region “A” in FIG. 4A. Referring to FIG. 4A, a photo mask 100 of the present embodiment includes a mask substrate 99 and mask patterns 101 which are used for forming fine patterns.
