Abstract
The invention provides a liquid crystal display panel which comprises an array substrate. The array substrate comprises multiple first-layer metal cables and multiple second-layer metal cables crossed with the first-layer metal cables in a stacked mode, each first-layer metal cable is electrically connected with the corresponding second-layer metal cable through a connecting hole, at each connecting hole, a first distance is formed between the adjacent second-layer metal cable of the second-layer metal cable where the connecting hole is located and the second-layer metal cable where the connecting hole is located, at the place without the connecting hole, a second distance is formed between the second-layer metal cable and the second-layer metal cable where the connecting hole is located, and the first distance is larger than the second distance. The liquid crystal display panel has the advantages that at each connecting hole, the distance between the second-layer metal cable and the second-layer metal cable where the connecting hole is located is increased, over etching affected areas of the connecting holes are bypassed, and therefore the situation that the meal cables become thin or are broken due to the fact that the connecting holes are subjected to over etching is avoided.
Description
Technical field
The present invention relates to field of liquid crystal display, particularly relate to a kind of display panels.
Background technology
Liquid crystal display is currently used widest a kind of flat faced display, has been increasingly becoming various electronic equipment as mobile

The display of resolution color/graphics.Along with the progress of LCD Technology, people to the display quality of liquid crystal display,
Appearance design, man machine interface etc. are had higher requirement.
Display appearance seems the most lucid and the most lively, holicholic, becomes the trend of liquid crystal display development；For easy to use with
And needs attractive in appearance, present digital product to small size, narrow frame, the demand such as ultrathin design is more and more urgent, and these
The behind of design, needs the support of a lot of technology, the such as requirement to the Metal cabling of the Array substrate of LCD more to come
The thinnest, gap is more and more less, and interlayer connection hole (VIA) is more and more less, and these bring certain will to production preparative capacibility
Challenge.
Fig. 1 show a kind of LCD technique, and first layer metal cabling M1 and second layer metal cabling M2 passes through connecting hole 10
Realize connecting.Its shortcoming is: in preparation process, can there are depression at connecting hole 10, and when upper strata, metal routing is closeer
In the case of, during etching processing procedure, between the second layer metal cabling M2 adjacent metal cabling at connecting hole 10, may deposit
Remaining at etch liquids, this by causing the phenomenon of over etching to the second layer metal cabling at connecting hole 10, such as Fig. 1 and Fig. 2
Shown in middle dotted line frame, particularly in the case of metal routing is relatively thin, disadvantages described above can cause the increase of trace resistances, seriously
Time may result in the disconnection of cabling, this will cause LCD normally not show, even can not show.
Summary of the invention
The technical problem to be solved is to provide a kind of display panels, and it is it can be avoided that connection hole over etching
The metal routing caused attenuates or breaks.
In order to solve the problems referred to above, the invention provides a kind of display panels, including array base palte, described array base palte
Including a plurality of first layer metal cabling and a plurality of second layer metal cabling cross-superimposed with described first layer metal cabling, each
Described first layer metal cabling is electrically connected by connecting hole with corresponding described second layer metal cabling, in each connection hole,
The second layer metal cabling adjacent with the second layer metal cabling at connecting hole place is walked to the second layer metal at described connecting hole place
Line has one first distance, at disconnected hole, and the second layer metal of this second layer metal cabling to described connecting hole place
Cabling has a second distance, and described first distance is more than described second distance.
Further, in each connection hole, the second layer metal adjacent with the second layer metal cabling at described connecting hole place is walked
Alignment bends away from the direction of the second layer metal cabling at described connecting hole place, to form the first distance.
Further, in each connection hole, the second layer metal cabling of all second layer metal cablings to described connecting hole place
Having one first distance, at disconnected hole, the second layer metal of all second layer metal cablings to described connecting hole place is walked
Line has a second distance, and described first distance is more than described second distance.
Further, in described each connection hole, all described second layer metals walk alignment away from the of described connecting hole place
The direction bending of two layers of metal routing, to form the first distance.
Further, in the second layer metal cabling the same side at described connecting hole place, all second layer metal cablings are equidistantly arranged
Cloth.
Further, at connection hole with disconnected hole, the second layer gold adjacent with the second layer metal cabling at connecting hole place
The width belonging to cabling is identical.
Further, in connection hole, the second layer metal cabling of the second layer metal cabling both sides being positioned at connecting hole place is symmetrical
Arrange.
It is an advantage of the current invention that in connection hole, the second layer metal cabling at second layer metal cabling and connecting hole place
Distance becomes big, has walked around the over etching influence area of connecting hole, thus the metal routing avoiding connection hole over etching to cause becomes
Thin or broken string.

Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the display panels that the present invention provides is elaborated.
Seeing Fig. 3, one display panels of the present invention, including array base palte, a plurality of first layer metal of described array base palte is walked
Line M1 and a plurality of second layer metal cabling M2 cross-superimposed with described first layer metal cabling M1.Each described ground floor
Metal routing M1 and corresponding described second layer metal cabling M2 is electrically connected by connecting hole 20, therefore, can exist multiple
Connecting hole 20, described connecting hole 20 is interspersed, and in this embodiment, only symbolically indicates two connecting holes
20.In figure 3, for the architectural feature of clear interpretation display panels of the present invention, by one of them connecting hole 20 place
Second layer metal cabling be labeled as M21, other second layer metal cablings are labeled as M2.
In this embodiment, described first layer metal cabling M1 is lower metal cabling, and described second layer metal is walked
Line M2 is upper strata metal routing.When making connecting hole 20, the second layer metal cabling M21 at connecting hole 20 is adjacent
Between metal routing, may there is etch liquids residual, the second layer metal cabling at connecting hole 20 will be caused over etching by this
Phenomenon, formed over etching region.
Display panels of the present invention is at each connecting hole 20, with the second layer metal cabling M21 phase at connecting hole 20 place
