Abstract

Disclosed is an FFS (Fringe Field Switching) mode liquid crystal display. The FFS mode liquid crystal display comprises: a lower substrate and an upper substrate; a gate line formed on the lower substrate; a data line crossing perpendicular to the gate line; a first ITO electrode formed in a region defined by the gate line and the data line; a second ITO electrode of a comb-teeth pattern formed on the lower substrate while being overlapped on the first ITO electrode; and a black matrix formed on the upper substrate, wherein, a wedge portion of the second ITO electrode is formed at a position spaced by a predetermined interval to the inside from an edge section of the black matrix.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the invention [0002] The present invention relates to a fringe field switching (hereinafter, simply referred to as “FFS”) mode liquid crystal display, and more particularly to an FFS mode liquid crystal display capable of improving driving mura and luminance non-uniformity. [0003] 2. Description of the Prior Art [0004] A method for fabricating an ultra-FFS mode liquid crystal display may be described as follows, with reference to FIGS. 1A and 1B. Herein, FIG. 1A is a plan view of a conventional ultra-FFS mode liquid crystal display, and FIG. 1B is a sectional view thereof. [0005] As shown in FIGS. 1A and 1B, according to the conventional ultra-FFS mode liquid crystal display, a gate line 11 and a data line 15 are aligned to cross perpendicular to each other on a lower substrate 10. Then, a first ITO electrode 17 is aligned in a region defined by the gate line 11 and the data line 15. After this, a second ITO electrode 19 for a pixel ele...
