The embodiment of the application provides a display panel and a display device. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Fig. 1 is a schematic structural diagram of a display panel 1 according to a first embodiment of the present disclosure, where as shown in the figure, the display panel 1 includes a display area 100, and the display panel 1 includes an array substrate 11, a color filter substrate 12, and a conductive structure 13. The first side surface 110 of the array substrate 11 is sequentially stacked with a black matrix 122 and a first common electrode layer 111, and the first common electrode layer 111 includes a first common electrode 111a located in the display area 100; the color filter substrate 12 is disposed opposite to the first side surface 110 of the array substrate 11, and a second common electrode layer 121 is disposed on a second side surface 120 of the array substrate 11, where the second common electrode layer 121 includes a second common electrode 121a located in the display area 100.
The conductive structure 13 is disposed between the array substrate 11 and the color filter substrate 12, the conductive structure 13 is located in the display area 100, one end of the conductive structure 13 is electrically connected to the first common electrode 111a, and the other end of the conductive structure 13 is electrically connected to the second common electrode 121 a.
By arranging the conductive structure 13 between the array substrate 11 and the color filter substrate 12, the first common electrode layer 111 on the array substrate 11 is electrically connected with the second common electrode layer 121 on the color filter substrate 12, the consistency of voltages on the first common electrode layer 111 and the second common electrode 121a can be improved, and horizontal crosstalk caused by the influence of voltage change on a data line on the voltages on the first common electrode layer 111 and the second common electrode layer 121 is reduced; the conductive structure 13 is disposed in the display area 100, so as to further reduce the influence of the voltage variation on the data line on the first common electrode 111a and the second common electrode 121a, which is beneficial to the alignment of the liquid crystal in the display area 100, and improve the display quality of the display panel 1.
In the embodiment provided in the present application, the second common electrode layer 121 is a transparent electrode, and the material of the transparent electrode is Indium Tin Oxide (ITO), so that the transparent electrode has good light transmittance and electrical conductivity.
As shown in fig. 1, the conductive structure 13 includes a supporting pillar 131 supported between the array substrate 11 and the color filter substrate 12, and a conductive portion 132 disposed on the supporting pillar 131, where the conductive portion 132 extends along a length direction of the supporting pillar 131, and one end of the conductive portion 132 is electrically connected to the first common electrode 111a, and the other end is electrically connected to the second common electrode 121 a.
By arranging the supporting columns 131 between the array substrate 11 and the color film substrate 12, when the display panel 1 is squeezed or impacted, the supporting columns 131 can limit the relative movement of the array substrate 11 and the color film substrate 12, so that the structural stability of the display panel 1 is enhanced. It should be noted that the conductive structure 13 may not include the supporting column 131, for example, the conductive structure 13 is a single conductive component, and the function of reducing horizontal crosstalk can be achieved as long as the electrical connection between the first common electrode 111a and the second common electrode 121a is achieved, and the specific embodiment is not limited herein.
As shown in fig. 1, in the embodiment provided in the present application, the conductive portion 132 is formed on the surface of the supporting pillar 131, the insulating layer 112 is disposed on the first common electrode layer 111, the first via hole 1120 is disposed on the insulating layer 112 at a position corresponding to the first common electrode 111a, and the conductive portion 132 passes through the first via hole 1120 and is electrically connected to the first common electrode 111 a. A passivation layer 112a may be further disposed on the insulating layer 112, and then a first via 1120 may be formed on the insulating layer 112 and the passivation layer 112a, such that the conductive portion 132 is electrically connected to the first common electrode 111a through the first via 1120.
The conductive portion 132 may not be formed on the surface of the supporting column 131, for example, the conductive portion 132 penetrates the supporting column 131, and one end thereof is electrically connected to the first common electrode 111a, and the other end thereof is electrically connected to the second common electrode 121 a. By forming the conductive portion 132 on the surface of the supporting post 131, the manufacturing process can be simplified, and the display panel 1 can be manufactured more easily. The cross-section of the supporting column 131 may be rectangular or trapezoidal, and the top end or the bottom end thereof may be circular, oval or polygonal, and is not limited herein.
In the embodiment provided in this application, as shown in fig. 1, the supporting pillar 131 is disposed on the color filter substrate 12, the conductive portion 132 includes a first conductive layer 1321 and a second conductive layer 1322, the first conductive layer 1321 is disposed on the insulating layer 112 and electrically connected to the first common electrode 111a through the first via 1120, the second conductive layer 1322 covers the supporting pillar 131 and electrically connected to the second common electrode 121a, and the first conductive layer 1321 and the second conductive layer 1322 abut against each other, so as to electrically connect the first common electrode 111a and the second common electrode 121 a.
As shown in fig. 1, the second conductive layer 1322 covers the outer peripheral surface and the end surface of the supporting pillar 131, and it should be noted that the second conductive layer 1322 and the first conductive layer 1321 are positioned such that the second conductive layer 1322 and the first conductive layer 1321 at the end surface of the supporting pillar 131 are in contact with each other.
It is to be understood that the second conductive layer 1322 and the second common electrode 121a may be disposed in the same layer or may not be disposed in the same layer. When the second conductive layer 1322 and the second common electrode 121a are disposed on the same layer, in a manufacturing process of the display panel 1, referring to fig. 1, the supporting pillar 131 is firstly manufactured on the color filter substrate 12, then the second common electrode 121a is formed on the color filter substrate 12, and the second common electrode 121a covers a surface of the supporting pillar 131, where the second common electrode 121a on the surface of the supporting pillar 131 is the second conductive layer 1322. Therefore, the second conductive layer 1322 and the second common electrode 121a are disposed in the same layer, which simplifies the manufacturing process and reduces the manufacturing cost.
It is understood that the position of the supporting column 131 can be adjusted according to actual conditions. Preferably, in the second embodiment provided in the present application, as shown in fig. 2, the position of the supporting column 131 corresponds to that of the first via 1120, that is, the supporting column 131 is directly opposite to the first via 1120, so as to increase a contact area between the second conductive layer 1322 and the first conductive layer 1321, which is beneficial to improving electrical connection performance between the first common electrode 111a and the second common electrode 121 a.
In the embodiment provided by the present application, as shown in fig. 2, the color-resist layer 113 is further disposed on the insulating layer 112, a second via hole 1130 is disposed on the color-resist layer 113 at a position corresponding to the first via hole 1120, and the first conductive layer 1321 passes through the first via hole 1120 and the second via hole 1130 and is electrically connected to the first common electrode 111 a.
The addition of the color resist layer 113 on the insulating layer 112 helps to reduce the width of the metal wiring on the array substrate 11, so that the light-transmitting area is increased. It should be noted that a planarization layer may be further disposed on the color resist layer 113 to planarize the surface of the array substrate 11, which is beneficial to alignment of the liquid crystal between the array substrate 11 and the color filter substrate 12.
In the third embodiment of the present application, as shown in fig. 3, the supporting pillars 131 are disposed on the array substrate 11 and are disposed to be offset from the first vias 1120; the conductive part 132 includes a third conductive layer 1323 and a fourth conductive layer 1324, the third conductive layer 1323 passes through the first via 1120 to be electrically connected to the first common electrode 111a, the fourth conductive layer 1324 is formed by extending from the third conductive layer 1323 along the side surface of the supporting pillar 131, and the fourth conductive layer 1324 is electrically connected to the second common electrode 121 a.
When the supporting pillars 131 are disposed on the array substrate 11, in the manufacturing process of the display panel 1, the supporting pillars 131 are firstly manufactured on the array substrate 11, and then the third conductive layer 1323 and the fourth conductive layer 1324 are manufactured; the third conductive layer 1323 passes through the first via 1120 to be overlapped with the first common electrode 111a, the third conductive layer 1323 extends along the side surface of the supporting column 131 to form a fourth conductive layer 1324, and the fourth conductive layer 1324 is overlapped with the second common electrode 121 a. Thereby, the first common electrode 111a and the second common electrode 121a are electrically connected through the third conductive layer 1323 and the fourth conductive layer 1324.
Note that the fourth conductive layer 1324 may be provided only on the side surface of the supporting column 131, or may cover the entire surface of the supporting column 131. Preferably, in the embodiments provided herein, the fourth conductive layer 1324 covers the surface of the supporting column 131, that is, as shown in fig. 3, the second conductive layer 1322 covers the side surface and the end surface of the supporting column 131, so that the contact area between the second conductive layer 1322 and the second common electrode 121a can be increased to improve the electrical contact performance between the first common electrode 111a and the second common electrode 121 a.
It is understood that when the supporting posts 131 are disposed on the array substrate 11, as shown in fig. 4, the color resist layer 113 may also be disposed on the insulating layer 112 of the array substrate 11 to increase the light-transmitting area of the display panel 1; a planarization layer may be further disposed on the color resist layer 113 to planarize the surface of the array substrate 11 and improve the alignment of the liquid crystal between the array substrate 11 and the color filter substrate 12.
