Specific embodiment
Further to illustrate technological means and its effect adopted by the present invention, below in conjunction with preferred implementation of the invention
Example and its attached drawing are described in detail.
Please refer to Fig. 2 and Fig. 3, the present invention provides a kind of structure of liquid crystal display panel, including tft array substrate 1, with
The CF substrate 2 that the tft array substrate 1 is oppositely arranged and the liquid being filled between the tft array substrate 1 and CF substrate 2
Crystal layer 3.
The first metal layer M1 and second metal layer M2 is equipped in the tft array substrate 1.Wherein, the first metal layer
M1 includes scan line (not indicating), the grid (not indicating) for constituting TFT and array substrate side public electrode 11 etc.；Described second
Metal layer M2 includes a plurality of data line 13 being parallel to each other and the source electrode and drain electrode (not the indicating) that constitute TFT etc..Specifically, institute
The material for stating the first metal layer M1 and second metal layer M2 is one of molybdenum (Mo), titanium (Ti), aluminium (Al), copper (Cu) or more
The stacked combination of kind.
The CF substrate 2 be equipped with it is multiple in array arrangement pixel electrodes 25 and a plurality of bucking electrode 23, one
A corresponding column pixel electrode 25 setting of bucking electrode 23, and the corresponding top for being located at a data line 13 of a bucking electrode 23 is simultaneously
Cover the data line 13.
In conjunction with Fig. 2 and Fig. 3, the bucking electrode 23 accesses CF substrate-side public voltage signal CFCOM, and by the CF base
Plate side public voltage signal CF COM is transmitted to 1 side of tft array substrate (by the way that gold is arranged in the end of bucking electrode 23
The mode of ball or open up via hole make bucking electrode 23 through via hole mode realize to 1 side of tft array substrate transmit common electrical
Press signal CF COM).In this way, on the one hand the bucking electrode 23 and array substrate side are public when liquid crystal display panel work
Electrode 11, which is formed by electric field, can make the partial liquid crystal layer 3 between the data line 13 and bucking electrode 23 keep not inclined
Turn state, light cannot penetrate, thus instead of the part black matrix" (Black being set to above data line in the prior art
Matrix, BM) light leakage is prevented, it can be described as DBS (DataLine BM-Less) design, and the pixel electrode 25 and array base
Plate side public electrode 11, which is formed by electric field, can make the part liquid crystal layer 3 corresponding to the pixel electrode 25 deflect,
Light is smoothly through to be shown；On the other hand, since the bucking electrode 23 is by the CF substrate-side public voltage signal
CF COM is transmitted to 1 side of tft array substrate, i.e., electrode 23 is covered described in as common voltage cabling, thus not necessarily like
Individual common voltage cabling is specially arranged in the prior art in the external zones of liquid crystal display panel like that, so that common voltage is walked
Line is not take up border width, therefore the border width of liquid crystal display panel can be made to reduce 20% or more, helps to realize liquid crystal
The narrow frame of display panel product,
Specifically, as shown in figure 3, the pixel electrode 25 is in " rice " font；The bucking electrode 23 and the pixel electricity
The material of pole 25 is tin indium oxide (Indium Tin Oxide, ITO).Although the electrical property of ITO is poor, a large amount of screen
Impedance after covering 23 parallel connection of electrode also can be smaller, can swimmingly be transmitted to the CF substrate-side public voltage signal CF COM
1 side of tft array substrate.
Structure of liquid crystal display panel of the invention, CF substrate is correspondingly arranged a covering above every data line should
The bucking electrode of data line, the bucking electrode access CF substrate-side public voltage signal, on the one hand to be located at the data
Partial liquid crystal layer between line and bucking electrode keeps not deflection state, prevents light leakage, is on the other hand used as common voltage cabling,
The CF substrate-side public voltage signal is transmitted to the tft array substrate side, to exist like that not necessarily like the prior art
Individual common voltage cabling is specially set in external zones, so that common voltage cabling is not take up border width, liquid can be reduced
The border width of LCD panel helps to realize the narrow frame of LCD display panel products.
The above for those of ordinary skill in the art can according to the technique and scheme of the present invention and technology
Other various corresponding changes and modifications are made in design, and all these change and modification all should belong to claim of the invention
Protection scope.
