In a first aspect, fig. 1 is a schematic structural diagram of a substrate 1 disclosed in an embodiment of the present application. As shown in fig. 1, the substrate 1 includes: a substrate 2; the black matrix 3 and the color resistors 4 are arranged on the substrate 2, the color resistors 4 are arranged in an array, and the black matrix 3 is positioned between two adjacent color resistors 4; a planarization layer 5, the planarization layer 5 covering the black matrix 3 and the color resists 4; and a plurality of spacers 6, the spacers 6 being disposed on a side of the planarization layer 5 remote from the substrate 2. The black matrix 3 and/or the spacer 6 in the embodiment of the present application include an excitation type water absorbing material for having water absorption when excitation is generated from the outside.
Since the black matrix 3 and/or the spacer 6 in the embodiment of the present application include the excitation type water absorbing material for absorbing water when excited by the outside, when the substrate in the embodiment of the present application is used as a cover plate of a display substrate, the excitation type water absorbing material may be excited to absorb water before or during packaging, so that the black matrix 3 and/or the spacer 6 has water absorption. Therefore, compared with the prior art, the embodiment of the application can effectively absorb moisture released after the color resists 4, the black matrix 3, the planarization layer 5 and the spacer 6 are packaged without changing the overall structure of the display panel, thereby improving the packaging reliability of the display panel.
Specifically, as shown in fig. 1, the black matrix 3 covers the edge area of the color resist 4, which can effectively prevent light leakage at the edges of the pixel. The color resistors 4 include a red color resistor (e.g., the color resistor 4 on the left side in fig. 1), a green color resistor (e.g., the color resistor 4 on the middle side in fig. 1), and a blue color resistor (e.g., the color resistor 4 on the right side in fig. 1), and of course, in practical applications, the color resistors may also include color resistors of other colors, and the application does not limit the color of the color resistor 4.
In a specific embodiment, as shown in fig. 1, the orthographic projection area of the spacer 6 on the substrate 2 is located in the orthographic projection area of the black matrix 3 on the substrate 2, and when the substrate in the embodiment of the present application is used as a package cover plate, the arrangement mode has low requirement on the light transmittance of the spacer 6, and can make the light transmittance of the display panel formed after packaging better.
Alternatively, the excitation type water absorbing material may be excited by heating or light irradiation, and specifically, the excitation type water absorbing material may be heated to have water absorbability, or may be irradiated with ultraviolet rays to have water absorbability, so that the black matrix 3 and/or the spacer 6 have water absorbability.
Optionally, in an embodiment, when the excitation type water absorbent material is heated, the heating temperature is less than 100 degrees celsius, and the heating time is less than 1 hour, in practical applications, if the heating temperature is too high, or the heating time is longer, the water absorption property of the excitation type water absorbent material may be reduced, and the use cost of the heating device may be increased, therefore, the heating temperature in the embodiment of the present application may be selected from 80 degrees celsius to 90 degrees celsius, and the heating time may be selected from 30 minutes to 50 minutes, so that the black matrix 3 and/or the spacer 6 have water absorption property.
Alternatively, in the present embodiment, the mass fraction of the excitation type water absorbing material in the black matrix 3 is greater than 1%. In another embodiment, the mass fraction of the excitation type water absorbing material in the spacer 6 is more than 1%; when the mass fraction of the excitation type water absorption material in the black matrix 3 and the spacer 6 is greater than 1%, the water absorption performance of the excitation type water absorption material in the embodiment of the present application can be better excited, and when the substrate in the embodiment of the present application is used as an encapsulation cover plate of a display substrate, moisture generated after encapsulation of the color resists 4, the black matrix 3, the planarization layer 5 and the spacer 6 can be better absorbed, so that the encapsulation reliability of the display panel is not affected.
Alternatively, in the present embodiment, the excitation type water absorbing material includes an epoxy-based material or a nano-based material. As the excitation type water absorbing material in this example, an epoxy material was selected, and the water absorption curve of the epoxy material without ultraviolet irradiation is shown in FIG. 2, the water absorption curve after ultraviolet irradiation is shown in FIG. 3, and both of FIGS. 2 and 3 are graphs obtained by performing experiments under conditions of a temperature of 25 ℃ and a humidity of 50%. As shown in fig. 2, the epoxy material has no water absorption property and cannot absorb any moisture when not irradiated by ultraviolet rays; as shown in fig. 3, the water absorption property of the epoxy-based material increases from 0.0% to nearly 2.5% within 4 hours after the ultraviolet irradiation, and the water absorption property is maintained all the time thereafter, and therefore, the black matrix 3 and/or the spacer 6 in the embodiment of the present application can absorb moisture in the display panel for a long time.
Alternatively, as shown in fig. 4, the black matrix 3 includes a first photoresist 7 and an excitation type water absorption material 8, and the excitation type water absorption material 8 is uniformly distributed in the first photoresist 7; the arrangement mode can ensure that the water absorptions of different areas of the black matrix 3 are the same, and effectively avoids the problem that the different areas of the black matrix 3 are deformed due to different water absorptions.
As shown in fig. 5, in another embodiment, the spacer 6 includes a second photoresist 9 and an excitation type water absorption material 8, and the excitation type water absorption material 8 is uniformly distributed in the second photoresist 9; similarly, the arrangement mode can ensure that the water absorbability of different areas of the shock insulator 6 is the same, and effectively avoids the problem that the different areas of the shock insulator 6 are deformed due to different water absorbability. Of course, the same material may be used for the first and second photoresists 7 and 9 in order to reduce manufacturing costs.
In one embodiment, the thickness of the color resists 4 is 0.1 to 5 microns in the orthographic projection direction of the substrate; the thickness of the black matrix 3 is 0.1 to 5 micrometers; the thickness of the planarization layer 5 is 0.1 to 5 micrometers; the spacer 6 has a thickness of 0.5 to 8 micrometers.
In a second aspect, the present application discloses a display panel, including the substrate 1 of the first aspect and an array substrate. The array substrate includes: the array substrate and the substrate 1 are correspondingly attached, and the substrate 1 is used for packaging the array substrate. Since the display panel of the second aspect includes the substrate 1 of the first aspect, the display panel has the same beneficial technical effects as the substrate 1. Therefore, the advantageous effects of the display panel of the second aspect are not repeated herein.
Specifically, the array substrate in the embodiment of the present application is a display substrate on which a pixel circuit and an organic light emitting device are fabricated, and the specific structure of the display substrate is similar to that of the prior art, and the display substrate does not relate to the improvement point of the present application, and therefore is not described herein again; the substrate 1 is used as a package substrate of the display substrate, and can ensure that the packaged display panel has good reliability.
In a third aspect, an embodiment of the present application discloses a display device, including: the display panel of the second aspect. Since the display panel of the third aspect includes the display panel of the second aspect, the display device has the same advantageous technical effects as the display panel. Therefore, the advantageous effects of the display device of the third aspect will not be repeated herein.
In a fourth aspect, the present embodiment discloses a method for manufacturing a substrate 1, as shown in fig. 6, the method including:
s101: a black matrix 3 and a plurality of color resistors 4 are manufactured on a substrate 2 through a composition process, the color resistors 4 are arranged in an array, and the black matrix 3 is positioned between two adjacent color resistors 4.

Since the manufactured black matrix 3 and/or the spacer 6 include the excitation type water absorbing material for absorbing water when excited by the outside, when the substrate manufactured in the embodiment of the present application is used as a cover plate of a display substrate, the excitation type water absorbing material may be excited to absorb water before or during packaging, so that the black matrix 3 and/or the spacer 6 have water absorption. Therefore, the embodiment of the application can effectively absorb moisture released after the color resists 4, the black matrix 3 layer, the planarization layer 5 and the spacer 6 are packaged without changing the overall structure of the display panel, thereby improving the packaging reliability of the display panel.
It should be noted that, after the excitation-type water absorbing material in the embodiments of the present application is excited by the outside, the water absorption property thereof is maintained, for example: after the excitation type water absorbing material is heated, the excitation type water absorbing material is converted into a water absorbing material capable of absorbing water in any case. The applicant of the present application considers that a simple water absorbing material is not easy to store, and can absorb moisture in air during the manufacturing and transferring processes, so that the effect of packaging water absorption cannot be achieved, and therefore, the embodiment of the present application selects an excitation type water absorbing material which needs external excitation and then has water absorption.

In specific implementation, the second photoresist 9 may be a positive photoresist, the excitation type water absorption material 8 may be an epoxy material, and the excitation type water absorption material 8 is doped in the second photoresist 9, which includes: and mixing the epoxy material into the positive photoresist and stirring to uniformly distribute the epoxy material in the positive photoresist, so as to ensure that different areas of the formed spacer 6 have the same water absorption.
When the substrate manufactured in the embodiment of the application is used for packaging a display substrate, the black matrix 3 and the spacer 6 can be subjected to heating treatment to excite the water absorption performance of the black matrix 3 and the spacer 6, and in specific implementation, the heating temperature is less than 100 ℃ and the heating time is less than 1 hour. Alternatively, in another embodiment, the black matrix 3 and the spacer 6 are subjected to ultraviolet irradiation treatment to excite the water absorbing property of the black matrix 3 and the spacer 6.
