In the prior art, most of display devices with display panels are often operated outdoors, so the display panels are more reliable in the external environment. Under the high-temperature and high-humidity condition, water vapor easily invades into the display area from the non-display area of the display panel and reacts with materials in the box to generate broken bright points; at present, based on analysis and experiments on the bad phenomenon, the main media for water vapor to permeate into the box (liquid crystal layer) to pollute liquid crystal molecules are the planarization layer and the alignment layer material, so that the invention of the novel display panel is urgently needed, and the problem that the display panel is easy to be invaded by water vapor in a high-temperature and high-humidity environment can be avoided.
In view of the above, the present invention provides a display panel and a display device, so as to solve the problem that the display panel is easily invaded by moisture under a high temperature and high humidity environment.

Specifically, the present application provides a display panel 100, where the display panel 100 includes a display area AA and a non-display area NA surrounding the display area AA, and the present application does not specifically limit the manner in which the non-display area NA surrounds the display area AA, and for example, the non-display area NA may surround the entire display area AA, or the non-display area NA may surround the display area AA in half. The present application is described taking as an example that the non-display area NA shown in fig. 1 surrounds the entire display area AA.
As shown in fig. 2, the display panel 100 includes an array layer 10, a liquid crystal layer 20 and a color film layer 30, wherein the liquid crystal layer 20 is disposed between the array layer 10 and the color film layer 30, and along a direction in which the color film layer 30 points to the array layer 10, that is, along a direction opposite to a light emitting direction of the display panel 100, the color film layer 30 includes a glass substrate 31, and a light shielding layer 32, a color resist layer 33 and a first thin film component 34 which are sequentially disposed at least on one side of the glass substrate 31, where the first thin film component 34 is a layer structure added to the display panel 100 in the present application, the first film assembly 34 is made of a hydrophobic material, that is, the first film assembly 34 has hydrophobicity, and can be used for blocking permeation of water vapor, specifically, blocking permeation of water vapor in a high-temperature and high-humidity environment from the non-display area NA to the display area AA, or specifically, the side of the first film element 34 away from the liquid crystal layer 20 can be blocked from water vapor entering the liquid crystal layer 20; thereby being beneficial to protecting the stability of the material of the liquid crystal layer 20 of the display panel 100, avoiding the situation that the liquid crystal in the box is polluted and being beneficial to ensuring the normal display effect of the display panel 100.
It should be noted that, the color film layer 30 provided herein only includes the light-shielding layer 32, the color resist layer 33 and the first film assembly 34, and is not used to limit the actual film layer structure included in the color film layer 30, and other required film layers may be further disposed in the color film layer 30, as long as the hydrophobic effect of the first film assembly 34 is not affected, and the moisture on the side of the first film assembly 34 far from the liquid crystal layer 20 can be prevented from invading into the liquid crystal layer 20, so as to ensure the normal display effect of the display panel 100.
It should be added that the liquid crystal layer 20 shown in fig. 2 is located on the non-display area NA side and further includes a sealant 21 for sealing liquid crystal molecules to form an integral liquid crystal layer structure. It should be noted that fig. 2 illustrates color resistors located in the display area AA in close contact with each other, which is only an exemplary drawing, and in an actual structure, there is a certain gap space between the color resistors, which is not limited in this application.
Referring to fig. 1 and 3, which are another cross-sectional views of AA' in fig. 1 provided in an embodiment of the present application, referring to fig. 1 and 3, optionally, the color film layer 30 further includes a planarization layer 35, and at least a portion of the planarization layer 35 is located between the color resist layer 33 and the first film assembly 34.
Specifically, the color film layer 30 provided by the present application may further include a planarization layer 35, where the planarization layer 35 may be at least disposed between the color resist layer 33 and the first film assembly 34, and is used to planarize the film layer structures (such as the light shielding layer 32 and the color resist layer 33) that have been fabricated before the first film assembly 34 is fabricated, so as to facilitate the fabrication of the first film assembly 34.
It should be noted that the planarization layer 35 may be specifically located between the light-shielding layer 32 and the first thin-film component 34, for example, as shown in fig. 3, the color film layer 30 includes the light-shielding layer 32 and the color resist layer 33, when a gap space is included between each color resist in the color resist layer 33, the gap may also be optionally filled by using the planarization layer 35, because there is a difference in height of the color resists respectively located in the display area AA and the non-display area NA, the planarization layer 35 is coated on a side of the color resist layer 33 away from the glass substrate 31, so that a surface of a side of the planarization layer 35 away from the glass substrate 31 in the color film layer 30 is a flat surface, and the first thin-film component 34 is conveniently manufactured on a side of the planarization layer 35 away from the glass substrate 31.
Because the manufacturing material used by the planarization layer 35 has the characteristic of hydrophilicity, the planarization layer 35 has stronger water absorption, if the planarization layer 35 absorbs excessive water vapor components in the external environment, when the first thin film assembly 34 with better hydrophobicity is arranged on the side of the planarization layer 35 close to the liquid crystal layer 20, the first thin film assembly 34 can block the water vapor stored in the planarization layer 35 from permeating into the liquid crystal layer 20, thereby being beneficial to protecting the stability of the liquid crystal layer 20 material in the display panel 100, avoiding the liquid crystal in the box from being polluted, and being beneficial to ensuring the normal display effect of the display panel 100.
Fig. 4-7 are cross-sectional views of AA' in fig. 1 according to an embodiment of the present disclosure, and referring to fig. 1 and 3-7, alternatively, the first film element 34 is located in the non-display area NA and the display area AA, where the thickness of the first film element 34 is D1, and the thickness of the first film element 34 in the display area AA is D2, and D1 > D2.
Specifically, the present application provides an alternative embodiment that the first thin-film element 34 is disposed in the whole display panel 100, that is, the first thin-film element 34 is disposed in the display area AA and the non-display area NA, as shown in fig. 3, when the planarization layer 35 is also disposed in the display area AA and the non-display area NA, the present application may dispose a first thin-film element 34 with a relatively thin thickness on the side of the planarization layer 35 away from the glass substrate 31, and the thickness of the whole first thin-film element 34 is, for example, between 0.07 μm and 0.2 μm, which can prevent moisture in the planarization layer 35 from permeating into the liquid crystal layer 20.
In addition to the side of the planarization layer 35 away from the glass substrate 31 shown in fig. 3 being a flat surface, the present application also provides a display panel 100 with an AA' cross section as shown in fig. 4, wherein the planarization layer 35 is disposed in both the display area AA and the non-display area NA, but the disposed thickness of the planarization layer 35 in the display area AA is greater than the disposed thickness of the planarization layer 35 in the non-display area NA, that is, the thickness of the planarization layer 35 in the display area AA shown in fig. 4 is H1, the thickness of the planarization layer 35 in the non-display area NA is H2, and H1 > H2; in this way of disposing the planarization layer 35, the first film assembly 34 on the side of the planarization layer 35 close to the liquid crystal layer 20 is required to be disposed as a flat surface, that is, the thickness of the first film assembly 34 in the display area AA is D2, and the thickness of the first film assembly 34 in the non-display area NA is D1, where D1 > D2. The first film assembly 34 in the non-display area NA is set to have a larger thickness, which is beneficial to preventing water vapor in the environment absorbed in the planarization layer 35 from permeating into the liquid crystal layer 20; the surface of the first film assembly 34 close to the liquid crystal layer 20 is made to be a flat surface, which is beneficial to modularity between the color film layer 30 and the liquid crystal layer 20.
It should be noted that the first film assembly 34 is located in the non-display area NA, specifically, the first film assembly 34 extends from the display area AA to the non-display area NA, and the first film assembly 34 is not limited to be located in the whole non-display area NA, as long as the first film assembly 34 with a certain width is located at a position of the non-display area NA close to the display area AA, so as to prevent moisture in the planarization layer 35 from permeating into the liquid crystal layer 20.
In an alternative embodiment, as shown in fig. 5, the first film element 34 is located in the non-display area NA and the display area AA, and the thickness of the first film element 34 in the non-display area NA is greater than that in the display area AA, for example, the thickness of the first film element 34 in the non-display area NA is D1, and the thickness in the display area AA is D2, where D1 > D2. As shown in fig. 5, the planarization layer 35 is disposed in the display area AA and the non-display area NA, the planarization layer 35 in the non-display area NA may be disposed only on a side of the non-display area NA close to the display area AA, and at this time, the first thin film element 34 may be disposed in an area of the non-display area NA away from the display area AA to directly contact the light-shielding layer 32, which is equivalent to the first thin film element 34 disposed around the planarization layer 35 in the non-display area NA, so that the first thin film element 34 can further block the water vapor on the side of the display panel 100 from penetrating through the planarization layer 35, which is more favorable for blocking the water vapor from penetrating into the display area AA from the non-display area NA of the display panel 100.
It should be noted that, the present application is not limited to the installation area of the planarization layer 35, for example, as shown in fig. 3,4, and 5, the planarization layer 35 may be installed in both the non-display area NA and the display area AA, or the planarization layer 35 may be installed only in the display area AA, and the installation area of the planarization layer 35 may be adjusted by a user according to actual needs.
FIG. 6 and FIG. 7 are cross-sectional views of another AA' in FIG. 1, referring to FIG. 1, FIG. 6 and FIG. 7, showing a planarization layer in the display area, the planarization layer having a thickness H, wherein D1 ≧ D2+ H.
Specifically, referring to fig. 6, when the first thin-film device 34 is located in the non-display area NA and the display area AA, and the thickness of the first thin-film device 34 in the non-display area NA is greater than that in the display area AA, the planarization layer 35 may be disposed only in the display area AA, and at this time, the first thin-film device 34 can serve as a planarization film layer structure in the whole non-display area NA, and has a hydrophobic effect; at this time, when the thickness of the planarization layer 35 disposed in the display area AA is H, the thickness D1 of the first film assembly 34 disposed in the non-display area NA is D2+ H. In non-display area NA, through adopting first film unit 34 to replace planarization layer 35, can enough play the effect of planarization membrane layer structure, can block again that non-display area NA keeps away from the infiltration of the external steam of display area AA one side to display area AA or even liquid crystal layer 20 to be favorable to protecting the stability of display panel 100 liquid crystal layer 20 material, avoid the contaminated condition of box interior liquid crystal to take place, be favorable to ensureing display panel 100's normal display effect.
Further, referring to fig. 7, when the first thin-film device 34 is located in the non-display area NA and the display area AA, the planarization layer 35 may be located only on a side of the color resist layer 33 away from the glass substrate 31 in the display area AA, where the entire non-display area NA (for example, a boundary between the non-display area NA and the display area AA is a side of the color resist in the display area AA close to the non-display area NA) or at least a portion of the entire non-display area NA and the display area AA can serve as a planarization film layer structure through the first thin-film device 34, and has a hydrophobic effect; at this time, when the thickness of the planarization layer 35 disposed in the display area AA is H, the thickness D1 > D2+ H of the first thin film assembly 34 disposed in the non-display area NA. In the non-display area NA, or in the non-display area NA and at least part of the display area AA, the first film assembly 34 is adopted to replace the planarization layer 35, so that the effect of planarizing the film layer structure can be achieved, and the external water vapor on one side, away from the display area AA, of the non-display area NA can be prevented from permeating into the display area AA and even the liquid crystal layer 20, so that the stability of the liquid crystal layer 20 material of the display panel 100 can be protected, the situation that liquid crystals in the box are polluted can be avoided, and the normal display effect of the display panel 100 can be guaranteed.
It should be noted that, when the height of each color resistance of the display area AA is relatively high, a flat layer 35 may be provided between the color resistance layer 33 and the first film member 34 of the display area AA. In the manufacturing process of the first thin film element 34 and the planarization layer 35, the manufacturing thickness of the first thin film element 34 is relatively thin, and the manufacturing thickness of the planarization layer 35 can be made very thick, so that a better planarization effect can be achieved for a color resistance with a higher height.
And from the process effect, the compactness of the first thin film assembly 34 is greater than that of the planarization layer 35, and can be used as a protective layer; the first film assembly 34 is added on the side of the planarization layer 35 of the display area AA away from the glass substrate 31, so that some ion exchange from the color film layer 30 to the liquid crystal layer 20 between the film layers can be prevented, and the liquid crystal inside the cell is prevented from being polluted.
Referring to fig. 2 to fig. 7, optionally, the orthographic projection of the first film assembly 34 on the light-emitting surface of the display panel 100 covers the display area AA and the non-display area NA.
Specifically, when the first thin film assembly 34 is disposed in the non-display area NA and the display area AA, except for the case that the first thin film assembly 34 is disposed on a side of the non-display area NA close to the display area AA, an alternative arrangement is provided in which the orthographic projection of the first thin film assembly 34 on the light-emitting surface of the display panel 100 covers the display area AA and the non-display area NA; since the liquid crystal molecules are also arranged in the non-display area NA in the display panel 100, and the liquid crystal molecules in the non-display area NA and the liquid crystal molecules in the display area AA are communicated, the first film assembly 34 covers the whole display area AA and the non-display area NA, the path area for blocking water vapor from entering can be increased, the situation that liquid crystal in the box is polluted is effectively avoided, and the normal display effect of the display panel 100 is favorably ensured.
It should be noted that, for the display area AA, the first film assembly 34 may completely cover the display area AA, or may partially cover the display area AA; similarly, for the non-display area NA, the first film assembly 34 may cover the non-display area NA completely or partially. The application does not specifically limit whether the coverage in the text is complete coverage or partial coverage, and the user can correspondingly adjust the coverage according to the actual situation. It should be noted that the cross-sectional views AA' in fig. 1 shown in fig. 2-7 are all examples, and no limitation is made on whether the first film assembly 34 is disposed in the entire non-display area NA or in a side area of the non-display area NA close to the display area AA, and the user can adjust the cross-sectional views accordingly.
Fig. 8 is another cross-sectional view of AA' in fig. 1 according to an embodiment of the present disclosure, and referring to fig. 1 and 8, the first film assembly 34 optionally includes a first sub-film 341 and a second sub-film 342;
the second sub-film member 342 is located on a side of the first sub-film member 341 away from the glass substrate 31.
Specifically, the first film assembly 34 disposed in the color film layer 30 of the present application may include a first sub-film member 341 and a second sub-film member 342, for example, as shown in fig. 8, the second sub-film member 342 may be disposed on a side of the first sub-film member 341 away from the glass substrate 31, and the first sub-film member 341 and the second sub-film member 342 are disposed adjacently.
Note that, when the planarization layer 35 is not separately provided in the display panel 100, the role of the planarization layer 35 may be replaced by, for example, the first sub-film member 341, and specifically, the first sub-film 341 may be located between the glass substrate 31 and the second sub-film 342, for example, when the color film 30 includes the light-shielding layer 32 and the color-resisting layer 33, when the color resists in the color resist layer 33 include a gap space therebetween, the gap space can be selectively filled with the first sub-film member 341, since there is a difference in the height of the color resists respectively disposed in the display area AA and the non-display area NA, the first sub-film 341 is thus applied to the side of the color-resist layer 33 remote from the glass substrate 31, therefore, the surface of the side of the first sub-thin film 341 away from the glass substrate 31 in the color film layer 30 is a flat surface, which is also beneficial to the fabrication of the second sub-thin film 342 on the side of the first sub-thin film 341 away from the glass substrate 31.
The method can also be understood that at least one first sub-thin film 341 is fabricated to planarize the film layer structure and simultaneously assist the second sub-thin film 342 to play a role in preventing water vapor from invading the liquid crystal layer 20 of the display panel 100, so as to further improve the performance of blocking water vapor, thereby being beneficial to protecting the stability of the liquid crystal layer 20 material of the display panel 100, preventing the liquid crystal in the cell from being polluted, and being beneficial to ensuring the normal display effect of the display panel 100.
