Detailed description of the invention
It, below will be to embodiment or the prior art in order to illustrate more clearly of embodiment or technical solution in the prior art
Attached drawing needed in description is briefly described, it should be apparent that, the accompanying drawings in the following description is only some of invention
Embodiment for those of ordinary skill in the art without creative efforts, can also be attached according to these
Figure obtains other attached drawings.
Fig. 1 is the schematic top plan view of the array substrate of liquid crystal display panel of the invention；
Fig. 2 is the schematic diagram of internal structure of liquid crystal display panel of the present invention.
Specific embodiment
The explanation of following embodiment is referred to the additional illustration, the particular implementation that can be used to implement to illustrate the present invention
Example.The direction term that the present invention is previously mentioned, such as [on], [under], [preceding], [rear], [left side], [right side], [interior], [outer], [side]
Deng being only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the present invention, rather than to
The limitation present invention.The similar unit of structure is with being given the same reference numerals in the figure.
The present invention is directed to existing liquid crystal display panel, and color membrane substrates are easy to produce in being bonded processing procedure with array substrate and lead
Charged particle so that the public electrode of liquid crystal display panel be connected to metal routing and short circuit and non-display area by spacer column branch
The technical issues of gap of support, color membrane substrates and array substrate is larger, leads to viewing area boundary light leakage or colour cast, the present embodiment
It is able to solve the defect.
As shown in Figure 1, the top view of the array substrate 101 for liquid crystal display panel of the invention, includes viewing area
102, it is non-display area 103 on the outside of the viewing area 102, the non-display area 103 is not used in display.
It include color membrane substrates 201 as shown in Fig. 2, being structure of liquid crystal display panel schematic diagram of the invention, the coloured silk film
Color blocking layer 202, black matrix" 203 and public electrode 204, the color blocking layer 202, black matrix" 203 are provided on substrate 201
In the lower surface of the color membrane substrates 201, the black matrix" 203 is prepared in 202 surface of color blocking layer, the public electrode
204 are located at the lower surface of the color blocking layer 202；It further include having array substrate 205, the viewing area setting of the array substrate 205
There are pixel electrode 206 and thin film transistor (TFT) array 207；There is gap 208 between the color membrane substrates 201 and array substrate 205,
It is provided with liquid crystal layer (not shown) in the gap 208, is set between the viewing area of the array substrate and the color membrane substrates
Several introns 209 are equipped with, the gap 208 has been used to support, and make each section high uniformity in gap 208.
The non-display area of the array substrate 205 is placed with several metal routings 210 for being used to control display, however, setting
209 bearing height of introns for being placed in the non-display area may be higher compared to 209 bearing height of introns of viewing area, into
And makes the part light leakage of close viewing area or colour cast occur；This is because part of the color membrane substrates 201 close to viewing area
It is slightly raised, causes the color blocking pixel on the color membrane substrates 201 to misplace with color blocking pixel bottom is corresponded to, so that light
Color blocking pixel cannot be injected according to ideal way, the light that liquid crystal layer penetrates only has part to enter color blocking pixel, goes out in color blocking pixel
Existing vacancy, another part light then seal in adjacent color blocking pixel, lead to colour cast occur.
Therefore liquid crystal display panel of the invention, the non-display area of the array substrate 205 are not provided with introns 209, from
And avoid and introns are set in the non-display area close to the array substrate 205, and raising the color membrane substrates 201 causes institute
State color blocking pixel on color membrane substrates 201 and misplace with the liquid crystal cell for corresponding to color blocking pixel bottom, prevent light from according to
Ideal way injects color blocking pixel, and the light that liquid crystal cell penetrates only has part to enter color blocking pixel, vacancy occurs in color blocking pixel, separately
A part of light then seals in adjacent color blocking pixel, leads to colour cast occur.
In liquid crystal display panel of the invention, the public electrode 204 avoids the metal routing 210 and is incident upon the coloured silk
View field in ilm substrate 201 and set；Further, by the public electrode, the color film is incident upon with the metal routing
The region of projection intersection on substrate uses laser cutting removal；At this point, being located at the color blocking layer of 204 upper surface of public electrode
The black matrix" 203 at 202 edges exposes, and the black matrix" 203 is corresponding to be located at 210 top of metal routing, the black
Matrix 203 has insulating properties, will not be electrically connected and lead because of conducting particles between the metal routing 210 and black matrix" 203
Short circuit is caused, and then influences the misoperation of display driving, by avoiding the indirect of the public electrode 204 and metal routing 210
Contact, to solve the problems, such as short-circuit due to generating conducting particles therebetween.
