Therefore, when the first organic light-emitting material layer is prepared, the third organic light-emitting sub-layer positioned on the shielding layer and the second organic light-emitting sub-layer positioned at the bottom of the groove can be naturally separated without external force, so that the path of water and oxygen diffusion is blocked, the water and oxygen are prevented from being diffused to the display area from the perforated area, and the service life of the display panel is prolonged.

The display panel covers the equipment body, and the photosensitive device is embedded into the opening of the opening region.
In this embodiment, the groove is disposed in the protection region between the display region and the opening region, so that the first organic light emitting sub-layer located outside the groove is separated from the second organic light emitting sub-layer located at the bottom of the groove, and thus, a path of water and oxygen diffusion can be blocked, and water and oxygen diffusion from the opening region to the display region can be avoided, which is beneficial to improving the service life of the display panel, and further, the organic light emitting material layer can be prevented from being cut off by laser firing, a thermal process can be omitted, so that the cracking failure and high equipment investment of the functional layer (driving circuit layer, second organic light emitting material layer, encapsulation layer) caused by too many particles or too high energy can be avoided, and the cost can be reduced. Moreover, because the first organic filling sub-layer exists on the second packaging sub-layer on the bottom of the groove, and the surface of the first organic filling sub-layer, which is far away from the first substrate, is flush with the surface of the first packaging sub-layer, which is located outside the groove, which is far away from the first substrate, in this way, the groove can be prevented from being damaged in the subsequent process, the wiring in the subsequent process can be prevented from being broken, and the bad bubbles can be prevented from occurring.
The display device in this embodiment may be: any product or component with a display function, such as electronic paper, a mobile phone, a tablet computer, a television, a notebook computer, a digital photo frame, a navigator and the like.
It is noted that in the drawings, the sizes of layers and regions may be exaggerated for clarity of illustration. Also, it will be understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element or layer or intervening layers may also be present. In addition, it will be understood that when an element or layer is referred to as being "under" another element or layer, it can be directly under the other element or intervening layers or elements may also be present. In addition, it will also be understood that when a layer or element is referred to as being "between" two layers or elements, it can be the only layer between the two layers or elements, or more than one intermediate layer or element may also be present. Like reference numerals refer to like elements throughout.
