Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the invention
  • 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.
  • 2. Description of the Prior Art
  • 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.
  • 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 electrode overlapped on a first ITO electrode 17 is fabricated in a comb-teeth pattern, and the orientation of liquid crystal is aligned at 0°.
  • Also, as shown in FIG. 1A, an upper substrate 20 is aligned opposite to the lower substrate 10, while being spaced from the lower substrate 10 by a predetermined interval, and a black matrix 21 is formed on the upper substrate 20. Herein, the second ITO electrode 19 for a pixel electrode overlapped on the black matrix 21 is lengthened by a length of ‘a’ to the outside from an edge section of the black matrix 21.
  • Owing to such a construction, when liquid crystal molecules are twisted by an electric field, upper liquid crystal molecules (a color filter substrate) and lower liquid crystal molecules (an array substrate) are twisted in opposite directions from each other, thereby compensating for chromatic shift toward a bluish color or a yellowish color, which is caused by dielectric anisotropy of the liquid crystal.
  • According to the conventional FFS mode liquid crystal display fabricated the above-mentioned method, since an overlapped region between electrodes is very wide, layers such as an insulation layer may be deteriorated due to long-period electrical operations, which results in inferior afterimages.
  • In order to correct such a disadvantage, various shapes and structures of electrodes have been studied and proposed.
  • However, according to conventional FFS pixels, a pixel wedge for the FFS pixels is not located in the black matrix but located in the real transmission region.
  • As a result, such a relationship between the pixel wedge and the black matrix causes transmittance reduction and luminance non-uniformity due to an alternation operation between them, so that the characteristics of manufactured goods are deteriorated.
    • SUMMARY OF THE INVENTION
  • Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide an FFS (Fringe Field Switching) mode liquid crystal display which can improve operating mura, luminance non-uniformity, etc., which have been problematic in the conventional FFS mode liquid crystal display, by establishing a new conception of mutual factors between a black matrix and a pixel electrode provided in an FFS design structure.
  • In order to accomplish this object, there is provided an FFS (Fringe Field Switching) mode liquid crystal display comprising: 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.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which:
  • FIG. 1A is a plan view of a conventional ultra-FFS mode liquid crystal display, and FIG. 1B is a sectional view thereof;
  • FIG. 2A is a layout view of an FFS mode liquid crystal display according to one embodiment of the present invention, and FIG. 2B is a sectional view of the FFS mode liquid crystal display shown in FIG. 2A; and
  • FIGS. 3 and 4 are schematic views for explaining FFS mode liquid crystal displays according to other embodiments of the present invention.
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. In the following description and drawings, the same reference numerals are used to designate the same or similar components, and so repetition of the description on the same or similar components will be omitted.
  • FIG. 2A is a layout view of an FFS (Fringe Field Switching) mode liquid crystal display according to one embodiment of the present invention, and FIG. 2B is a sectional view of the FFS mode liquid crystal display according to this embodiment of the present invention.
  • FIGS. 3 and 4 are schematic views for explaining FFS mode liquid crystal displays according to other embodiments of the present invention, in which a wedge portion of a second ITO electrode is formed with removed parts spaced from each other, so as to improve distortion of liquid crystal.
  • As shown in FIGS. 2A and 2B, according to an FFS mode liquid crystal display of one embodiment of the present invention, a gate line 31 and a data line 35 are aligned to cross perpendicular to each other on a lower substrate 30. Then, a first ITO electrode 37 is aligned in a region defined by the gate line 31 and the data line 35. After this, a second ITO electrode 39 for a pixel electrode, which is overlapped on a first ITO electrode 37, is fabricated in a comb-teeth pattern, and the orientation of liquid crystal is aligned at 0°.
  • In addition, as shown in FIG. 2B, an upper substrate 40 is aligned opposite to the lower substrate 30, while being spaced from the lower substrate 30 by a predetermined interval, and a black matrix 41 is formed on the upper substrate 40. Herein, the second ITO electrode 39 for a pixel electrode overlapped on the black matrix 21 is formed while being spaced by a length of ‘b’ to the inside from an edge section of the black matrix 21, different from the conventional construction.
  • Meanwhile, according to other embodiments of the present invention, as shown in FIGS. 3 and 4, a wedge portion of the second ITO electrode 59 or 69 is formed with removed parts spaced from each other, so that distortion of liquid crystal is improved.
  • As described above, according to the FFS mode liquid crystal display of the present invention, the location and the shape of the wedge portion is changed, so as to improve distortion of the liquid crystal which is caused by an electric field interference between the black matrix and the wedge portion. That is, the wedge portion of the second ITO electrode having a comb-teeth pattern is located within a region of the conductive black matrix, thereby improving the polarization efficiency of the liquid crystal, mura, luminance non-uniformity and afterimages (that is, unstableness of the liquid crystal according to an unstable operation) generated in a gray region of the wedge portion.
  • Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
