Fig. 2 is a schematic structural diagram of an lcd panel according to an embodiment of the present invention, and as shown in fig. 2, the lcd panel 100 includes: a display area 101 and a non-display area 102 surrounding the display area; the liquid crystal display panel 100 further includes a first substrate 110 and a second substrate 120 disposed oppositely, and a glue frame 130 and a liquid crystal layer 140 located between the first substrate 110 and the second substrate 120; the rubber frame 130 is positioned in the non-display area 102 and surrounds the display area 101; the liquid crystal layer 140 is located in a closed space surrounded by the first substrate 110, the second substrate 120 and the frame 130.
It is understood that the display area 101 of the liquid crystal display panel 100 includes a display unit, and the display unit may be composed of a color resistance, a pixel electrode, a pixel circuit, and the like of a corresponding color. In general, the color resists are disposed in the CF substrate, and the pixel electrodes and the pixel circuits are disposed in the TFT array substrate. The liquid crystal layer 140 of the display area 101 includes a liquid crystal compound 141, and an alignment direction of the liquid crystal compound 141 changes with a change of an electric field, thereby changing a luminous flux of the display area 101. The frame 130 is disposed in the non-display region 102, and the frame 130, the first substrate 110 and the second substrate 120 form a space for accommodating the liquid crystal compound 141, so as to isolate the liquid crystal layer 140 from the outside and protect the liquid crystal layer 140 from the external environment.
In the embodiment of the present invention, when the first substrate 110 is a CF substrate, the second substrate 120 may be a TFT array substrate; in contrast, when the second substrate 120 is a CF substrate, the first substrate 110 may be a TFT array substrate, and the structure of the first substrate 110 and the second substrate 120 is not particularly limited in the embodiment of the present invention. For convenience of understanding, the embodiment of the invention will be described by taking the first substrate 110 as a CF substrate and the second substrate 120 as a TFT array substrate.
With reference to fig. 2, a first alignment film 150 is disposed on a side of the first substrate 110 close to the liquid crystal layer 140, and correspondingly, a second alignment film 160 is disposed on a side of the second substrate 120 close to the liquid crystal layer 140, and the first alignment film 150 and the second alignment film 160 cooperate with each other to align the liquid crystal compound 141 of the liquid crystal layer 140; the material of the first alignment film 150 and the second alignment film 160 may include a high molecular polymer, such as Polyimide (PI). Under the influence of the materials for preparing the first alignment film 150 and the second alignment film 160, the first alignment film 150 and the second alignment film 160 are very easy to be used as the transmission path of water and oxygen.
In the embodiment of the invention, by providing at least one first opening 151 in the first alignment film 150 in the non-display region 102, and positioning at least a portion of the rubber frame 130 in the first opening 151, and in a direction Z perpendicular to the plane of the first substrate 110, the rubber frame 130 overlaps both the first alignment film 150 on the side of the first opening 151 close to the display region 101 and the first alignment film 150 on the side of the first opening 151 away from the display region 101. Thus, the existence of the first opening 151 enables at least part of the first alignment film 150 of the non-display area 102 and the first alignment film 150 of the display area 101 to be disconnected from each other, so as to reduce the transmission path of water and oxygen, and the first opening 151 includes at least part of the glue frame 130, part of the glue frame 130 is in direct contact with the first substrate 110, further isolating part of the first alignment film 150 of the non-display area 102 from being connected with part of the first alignment film 150 of the display area 101, so as to reduce water and oxygen entering the display area 101 of the liquid crystal display panel 100, so as to prevent more water and oxygen entering the liquid crystal display panel 100, and perform electrochemical corrosion on the device structure, signal lines and the like of the display area 101 of the liquid crystal display panel 100, thereby improving the display effect and the service life of the liquid crystal display panel 100; in addition, the rubber frame 130 overlaps the first alignment film 150 at the first opening 151, so that the rubber frame 130 contacts the first alignment film 150 and the first substrate 110 at the same time, the bonding area of the rubber frame 130 is increased, and the connection stability between the rubber frame 130 and the first substrate 110 is improved.
It should be noted that fig. 2 is only an exemplary diagram of the embodiment of the present invention, and fig. 2 only illustrates that the rubber frame 130 has an overlap with the first alignment film 150 on the side of the first opening 151 close to the display region 101 and the first alignment film 150 on the side of the first opening 151 away from the display region 101; and in the embodiment of the present invention, it is not limited to the case shown in fig. 2.
Exemplarily, as shown in fig. 3, the rubber frame 130 only overlaps the first alignment film 150 on the side of the first opening 151 away from the display region 101; alternatively, as shown in fig. 4, the rubber frame 130 only overlaps the first alignment film 150 on the side of the first opening 151 close to the display region 101. It can be understood that, no matter the rubber frame 130 overlaps the first alignment film 150 on the side of the first opening 151 close to the display region 101 and/or overlaps the first alignment film 150 on the side of the first opening 151 close to the display region 101, the first alignment film 150 of a part of the non-display region 102 and the first alignment film 150 of a part of the display region 101 are not connected to each other, so as to reduce the water and oxygen entering the display region 101 of the liquid crystal display panel 100; meanwhile, the adhesive area of the rubber frame 130 can be increased, and the connection stability between the rubber frame 130 and the liquid crystal display panel 100 can be improved.
For convenience of description, without any special limitation, the embodiments of the present invention take the overlapping condition of the rubber frame 130 and the first alignment film 150 shown in fig. 2 as an example, and exemplarily explain technical solutions of the embodiments of the present invention.
Optionally, with continued reference to fig. 2, water-absorbing particles 131 are disposed within the glue frame 130. The water absorption particles 131 in the rubber frame 130 can absorb water molecules, so that when the water molecules are transmitted to the position of the rubber frame 130 from the outside, the water absorption particles 131 in the rubber frame 130 can fully absorb water vapor, thereby further reducing the water vapor entering the circuit area and/or the display area, reducing the probability of electrochemical corrosion of devices in the circuit area and/or the display area due to water and oxygen, improving the display effect of the liquid crystal display panel 100, and prolonging the service life of the liquid crystal display panel 100.
In the embodiment of the present invention, the first alignment film 150 may include one or more first openings 151, and the position distribution and the area size of the first openings 151 are not particularly limited in the present invention on the premise that the transmission path of water and oxygen can be reduced. For example, as shown in fig. 2, the first opening 151 may be disposed only on a side of the circuit layout region in the non-display region 102 away from the display region 101, or the first opening 151 may also be disposed around the display region 101, which is not specifically limited in the embodiment of the present invention. Optionally, fig. 5 is a schematic bottom view of a first substrate according to an embodiment of the present invention. As shown in fig. 5, the first alignment film 150 includes a plurality of first openings 151, and the first openings 151 are arranged in a direction surrounding the display region 101. Thus, the first openings 151 are uniformly distributed around the display area 101, so that the first alignment films 150 in all directions in the display area 101 have fewer water and oxygen transmission paths, further transmission of partial water and oxygen is blocked in all directions of the display area 101, the probability of electrochemical corrosion of the circuit area and/or the device of the display area 101 due to water and oxygen is reduced, the display effect of the liquid crystal display panel 100 is improved, and the service life of the liquid crystal display panel 100 can be prolonged.
It should be noted that fig. 5 is a schematic diagram of an embodiment of the present invention, and fig. 5 shows a case where the first opening 151 is rectangular, but the first opening 151 may have other shapes in the implementation of the present invention, for example, the first opening 151 may also have a circular shape, an L shape, a U shape, an annular shape, and the like, which is not limited in the embodiment of the present invention.
Optionally, fig. 6 is a schematic bottom view of another first substrate according to an embodiment of the present invention. As shown in fig. 6, the liquid crystal display panel 100 has at least one first opening 151 surrounding the display region 101. At this time, the first opening 151 is a ring structure surrounding the display region 101.
In this way, by providing the first opening 151 surrounding the display area 101 in the non-display area 102, the first alignment film 150 on both sides of the first opening 151 can be completely divided, so that when water and oxygen enter the first alignment film 150 on the side of the first opening 151 away from the display area 101 from the edge of the liquid crystal display panel, the water and oxygen cannot be further transmitted to the first alignment film 150 on the side of the first opening close to the display area 101 due to the first opening 151, that is, the water and oxygen cannot be further transmitted to the display area 101, thereby preventing corrosion phenomena of devices, signal lines and the like in the liquid crystal display panel 100 caused by the transmission of the external water and oxygen by the first alignment film 150, and further effectively improving the display effect and the service life of the liquid crystal display panel 100.
It is to be understood that fig. 5 and 6 only exemplarily show the first opening of the first alignment film, the first alignment film may further include other first openings, and the position, shape and number of the other first openings are not particularly limited in the embodiment of the present invention.

In the direction Z perpendicular to the plane of the second substrate 120, the rubber frame 130 overlaps both the second alignment film 160 on the side of the second opening 161 close to the display region 101 and the second alignment film 160 on the side of the second opening 161 far from the display region 101.
In this way, the first alignment film 150 is provided with at least one first opening 151 and the second alignment film 160 is also provided with at least one second opening 161, such that the first alignment film 150 of the non-display region 102 is at least partially not connected to the first alignment film 150 of the display region 101, and the second alignment film 160 of the non-display region 102 is at least partially not connected to the second alignment film 160 of the display region 101, such that external water and oxygen cannot be transmitted from the first alignment film 150 on the side of the first opening 151 away from the display region 101 to the first alignment film 150 on the side of the first opening 151 close to the display region 101 across the first opening 151, and also cannot be transmitted from the second alignment film 160 on the side of the second opening 161 away from the display region 101 to the second alignment film 160 on the side of the second opening 161 close to the display region 101 across the second opening 161, thereby further reducing the transmission path of water and oxygen; the first opening 151 and the second opening 161 both include at least a portion of the rubber frame 130, the portion of the rubber frame 130 is in direct contact with the first substrate 110 and the second substrate 120, the connection between the first alignment film 150 of the portion of the non-display region 102 and the first alignment film 150 of the portion of the display region 101 is further isolated, and the connection between the second alignment film 160 of the portion of the non-display region 102 and the second alignment film 160 of the portion of the display region 101 is further isolated, so that the water and oxygen entering the display region 101 of the liquid crystal display panel 100 is further reduced, the situation that more water and oxygen enters the liquid crystal display panel 100 is prevented, and electrochemical corrosion is performed on the device structure, the signal lines and the like of the display region 101 of the liquid crystal display panel 100, so that the display effect and the service life of the liquid crystal display panel 100 are improved; in addition, the rubber frame 130 overlaps the first alignment film 150 at the first opening 151, and the rubber frame 130 overlaps the second alignment film 160 at the second opening 161, so that the rubber frame 130 is simultaneously in contact with the first alignment film 150, the first substrate 110, the second alignment film 160 and the second substrate 120, the bonding area of the rubber frame 130 on the side close to the first substrate 110 and the side close to the second substrate 120 is increased, and the connection stability of the rubber frame 130 with the first substrate 110 and the second substrate 120 is further improved.
It should be noted that fig. 7 is only an exemplary diagram of the embodiment of the present invention, and fig. 7 only illustrates that the rubber frame 130 has an overlap with the second alignment film 160 on the side of the second opening 161 close to the display region 101 and the second alignment film 160 on the side of the second opening 161 away from the display region 101; and in the embodiment of the present invention, it is not limited to the case shown in fig. 7.
Exemplarily, as shown in fig. 8, the rubber frame 130 only has an overlap with the second alignment film 160 on the side of the second opening 161 away from the display region 101; alternatively, as shown in fig. 9, the rubber frame 130 only overlaps the second alignment film 160 on the side of the second opening 161 close to the display region 101. It can be understood that no matter the rubber frame 130 and the second alignment film 160 of the second opening 161 near the display area 101 are overlapped, and/or the second alignment film 160 of the second opening 161 near the display area 101 is overlapped, the second alignment film 160 of the partial non-display area 102 and the second alignment film 160 of the partial display area 101 can be disconnected from each other, so as to reduce the water and oxygen entering the display area 101 of the liquid crystal display panel 100, and at the same time, the adhesive area of the rubber frame 130 can be increased, and the connection stability between the rubber frame 130 and the second substrate 120 can be improved.
