Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
The prior art has the technical problems of poor conductivity of a common electrode, slow potential resetting of the common electrode, easy occurrence of horizontal crosstalk, low aperture opening ratio and the like.
Accordingly, embodiments of the present invention provide a liquid crystal display panel and a method for manufacturing the liquid crystal display panel, which are described in detail below.
First, an embodiment of the invention provides a liquid crystal display panel, as shown in fig. 2, which is a schematic structural diagram of the liquid crystal display panel in an embodiment of the invention. The liquid crystal display panel includes: a first substrate base 201; a common electrode 204 disposed on one side of the first substrate 201; a metal light shielding layer 202 disposed on a side of the first substrate 201 away from the common electrode 204; and a conductive ball 203 disposed between the common electrode 204 and the metal light shielding layer 202 to connect the common electrode 204 and the metal light shielding layer 202.
Compared with the existing liquid crystal display panel, the metal light shielding layer 202 replaces a black matrix in the liquid crystal display panel, and the conductive balls 203 are used for connecting and conducting the metal light shielding layer 202 and the common electrode 204, and as the square resistance of the metal light shielding layer 202 is smaller than that of the common electrode 204, the metal light shielding layer 202 and the common electrode 204 are connected in parallel, the resistance of the common electrode 204 is reduced, the conductivity is increased, the speed of restoring to the initial potential is high when the metal light shielding layer 202 is interfered by signals, the capacity of improving the anti-interference capacity of the common electrode 204 and reducing the risk of horizontal crosstalk is high, meanwhile, the process precision of the metal light shielding layer 202 is high, the pixel display area is not easy to generate offset shielding, and the aperture ratio is improved effectively.
On the basis of the above embodiment, the liquid crystal display panel further includes a second substrate 206, a color filter layer 207, and an insulating protection layer 205, where the second substrate 206 is disposed opposite to the first substrate 201, the color filter layer 207 is disposed on a side of the second substrate 206 close to the first substrate 201, and the insulating protection layer 205 is disposed on a side of the metal light shielding layer 202 away from the first substrate 201.
Since the metallic light-shielding layer 202 and the common electrode 204 are respectively deposited on two sides of the first substrate 201 in this embodiment, compared to the prior art in which the black matrix and the common electrode are deposited on the same side of the glass substrate, the thickness of the metallic light-shielding layer 202 is generally 2 to 3 times of the thickness of the black matrix in the prior art due to the process limitation of preparing the metallic light-shielding layer 202, if the positions of the first substrate 201 and the second substrate 206 are not changed, the distance between the common electrode 204 and the second substrate 206 is reduced, the parasitic capacitance is increased, the influence on the scan lines and the signal lines is great, if the distance between the common electrode 204 and the second substrate 206 is kept unchanged, the distance between the first substrate 201 and the second substrate 206 is increased, and the usage amount of liquid crystal is increased, the production cost is also increased. In order to improve this phenomenon, the position of the metal light shielding layer 202 is optimized, at least one through hole is opened in the first substrate 201, and the conductive ball 203 is filled in the through hole. That is, the distance between the first substrate 201 and the substrate 206 is not changed, the black matrix is replaced with the metal light-shielding layer 202, and the conductive balls 203 are added to conduct the common electrode 204 and the metal light-shielding layer 202.
Preferably, the metal light shielding layer 202 is a metal layer formed with a plurality of openings spaced from each other. The pattern of the metal light shielding layer 202 is a plurality of opaque metal strips arranged in rows and columns, and the opaque metal strips are perpendicular to each other, and the arrangement positions of the metal strips distributed perpendicular to each other correspond to the positions of the data lines and the gate lines. And color filter layers 207 are correspondingly distributed among the metal strips. Meanwhile, the metal light shielding layer 202 is made of a metal material, and generally the sheet resistance of the metal material is much smaller than that of the common electrode 204, and preferably, the metal light shielding layer 202 is at least one of aluminum, copper, molybdenum or titanium. More preferably, the conductive ball 203 is also made of a metal material, and is made of at least one of the above metal materials, so that the sheet resistance of the conductive ball 203 is also much smaller than that of the common electrode 204.
In the embodiment of the present invention, in order to avoid that the conductive balls 203 block the display area of the pixel to reduce the aperture ratio, the projection of the conductive balls 203 on the common electrode 204 coincides with the projection of the metal light shielding layer 202 on the common electrode 204. At this time, the projection area of the conductive ball 203 on the common electrode 204 is smaller than or equal to the projection area of the metal light shielding layer 202 on the common electrode 204, the projection corresponding to the conductive ball 203 is completely covered by the projection corresponding to the metal light shielding layer 202, the conductive ball 203 coincides with the metal line position in the metal light shielding layer 202, and the display area is not additionally shielded, that is, the aperture ratio of the pixel is the same as the aperture ratio of only the metal light shielding layer 202.
Preferably, the material of the common electrode is indium tin oxide.

In some embodiments, the manufacturing method further includes manufacturing an insulating protection layer 205 on a surface of the metal light shielding layer 202 away from the first substrate 201, so as to protect the metal light shielding layer 202 from abrasion or corrosion during the manufacturing process, as shown in fig. 4E.
