Fig. 1 is a schematic partial structure diagram of a display device in the prior art, and as shown in fig. 1, the display device includes a display substrate, an encapsulation adhesive 52, and an encapsulation layer 9. The display substrate comprises a substrate 4, a display structure layer 5 and an organic light-emitting function layer 6 which are sequentially arranged. In the prior art, if a hole needs to be drilled in a display device, the sidewall of the through hole needs to be encapsulated to prevent water and oxygen from entering the inside of the display substrate to cause poor display. The substrate 4 is provided with a light emitting device, the light emitting device includes an organic light emitting function layer such as a light emitting layer, an electron transport layer, an electron injection layer, etc., wherein a portion of the organic light emitting function layer is formed by a whole surface evaporation method, so that the organic light emitting function layer 6 also exists in a packaging area, in a packaging process, bubbles 53 are generated in a contact area between the packaging glue 52 and the organic light emitting function layer 6, and the bubbles 53 cause a gap to exist in the contact area between the packaging glue 52 and the organic light emitting function layer 6, resulting in poor packaging.
Based on this, an embodiment of the present invention provides a display substrate, and fig. 2 is a top view of the display substrate provided in the embodiment of the present invention, as shown in fig. 2, the display substrate is divided into a hole punching area 1, a display area 2 surrounding the hole punching area 1, and a packaging area 3 located between the hole punching area 1 and the display area 2, and the packaging area 3 is used for disposing a packaging adhesive. Fig. 3 is a longitudinal sectional view taken along a sectional line AA' of fig. 2 according to an embodiment of the present invention, as shown in fig. 3, showing that the substrate includes: the display device comprises a substrate 4, a display structure layer 5 arranged on the substrate 4 and an organic light-emitting function layer 6 arranged on one side of the display structure layer 5, which is far away from the substrate. The organic light emitting functional layer 6 covers the display region 1 and the encapsulation region 3. A recess 51 is provided on the display structure layer 5 in the encapsulation area 3, and a portion of the organic light emitting function layer 6 is located in the recess 51.
Specifically, the punching area 1 is provided with a through hole penetrating through the display substrate, and the punching area 1 may be located in a central area of the display substrate (as shown in fig. 2) or in other areas of the display substrate, which is not limited herein. The display structure layer 5 may include a flat layer, and a plurality of film layers between the flat layer and the substrate base plate 4. The organic light emitting functional layer 6 may be one or more of an Electron Transport Layer (ETL), an Electron Injection Layer (EIL), a Hole Injection Layer (HIL), and a Hole Transport Layer (HTL).
With the display substrate according to the embodiment of the present invention, the groove 51 is formed in the display structure layer 5 in the encapsulation region 3, and a portion of the organic light emitting functional layer 6 is located in the groove 51, so that when the encapsulation adhesive is provided in the encapsulation region 3, a contact region between the encapsulation adhesive and the organic light emitting functional layer 6 can be located in the groove 51. In the packaging process, at least a part of the bubbles generated by the organic light-emitting functional layer 6 can be controlled in the groove 51, so that the gap between the organic light-emitting functional layer and the packaging adhesive is positioned in the groove due to the bubbles, and the packaging adhesive which does not fall into the groove can still have a good blocking effect on external water vapor, thereby improving the sealing performance of the display substrate package.
In some embodiments, the recess 51 is a continuous structure surrounding the perforation area 1. When the continuous structure is an annular structure, the orthographic projection of the groove 51 on the substrate 4 can be the same as the orthographic projection range of the encapsulation area 3 on the substrate, so that the contact areas of the encapsulation glue and the organic light-emitting functional layer 6 at various positions in the encapsulation area 3 are all located in the groove 51.
In the embodiment of the present invention, the cross section of the groove 51 may be gradually reduced, for example, the longitudinal section of the groove 51 may be an inverted trapezoid, and the width of the top opening of the groove 51 may be the same as the width of the encapsulation area 3 in this direction.
Fig. 4 is a schematic structural diagram of the display substrate and the encapsulation adhesive and the encapsulation layer thereon according to the embodiment of the present invention, as shown in fig. 4, the display structure layer 5 includes a flat layer 54 and a plurality of film layers 55, and the flat layer 54 is located on a side of the plurality of film layers 55 away from the substrate 1. The recess 51 is located on the planarization layer 54. A pixel defining layer 7 is arranged between the organic light-emitting function layer 6 and the flat layer 54, and a spacer 8 is arranged on the side, away from the substrate base plate 4, of the pixel defining layer 7. The pixel defining layer 7 and the spacer 8 are both located in the display area 2. In the embodiment of the present invention, the depth and the shape of the groove 51 may also be adjusted, for example, an included angle between the side wall and the bottom wall of the groove 51 is made as large as possible, so that a portion of the organic light emitting functional layer 6 located in the groove 51 during the evaporation process mainly covers the bottom wall of the groove 51, and only a small amount of or no organic light emitting functional layer 6 exists on the side wall of the groove 51, and therefore, a contact area between the encapsulation adhesive 52 and the organic light emitting functional layer 6 is located at the bottom of the groove 51, so that bubbles 53 at a boundary of the contact area between the encapsulation adhesive 52 and the organic light emitting functional layer 6 are further reduced.
Specifically, the pixel defining layer 7 may include a plurality of banks which are criss-crossed to define a plurality of pixel openings, and a portion of the organic light emitting functional layer 6 is located in the pixel openings and another portion is located on a side of the banks facing away from the base substrate 4. In addition, a light emitting layer, for example, a red light emitting layer, a green light emitting layer, a blue light emitting layer, or a white light emitting layer may be provided in the pixel opening.

In the embodiment of the present invention, the organic light emitting function layer 6 covering the encapsulation region 3 and the display region 2 may be an electron transport layer and an electron injection layer.
In the embodiment of the present invention, the pixel defining layer 7 and the spacer 8 may be located only in the display region 2, and the organic light emitting functional layer 6, the planarization layer 54 may be located in the display region 2 and the encapsulation region 3. Therefore, when the display substrate is manufactured, only the patterns of the mask plate for forming the planarization layer 54, the pixel defining layer 7 and the spacer 8 need to be changed, and other processes do not need to be changed, so that the manufacturing process is simplified.
Based on the same inventive concept, the embodiment of the invention further provides a display device, which comprises the display substrate and the packaging adhesive arranged in the packaging area of the display substrate. Wherein, the packaging adhesive is glass adhesive (frit adhesive).
