Under the condition that the polarizer 122 is adhered to the cover plate 110 by the first optical cement 140, the first optical cement 140 covers the second light shielding layer 1212 and the other part of the surface of the polarizer 122 facing the cover plate 110 except the second light shielding layer 1212.
Further, the color filter substrate 120 further includes a touch layer 123 disposed on a side of the polarizer 122 away from the cover plate 110, and the first light-shielding layer 1211 also covers a side wall of the touch layer 123 close to the channel C.
The display panel in this embodiment is a touch display panel, and the color Film substrate 120 includes a touch layer 123, where as shown in fig. 4, the touch layer 123 includes a cyclic olefin polymer (COP Film) layer 1231, and a touch sensing electrode 1232, a metal layer 1233, an insulating layer 1234, a transparent electrode layer 1235, and a passivation layer 1236 located on one side of the cyclic olefin polymer layer 1231 close to the polarizer 122.

Wherein the thickness of the third light-shielding layer 1213 may be in the range of 1.2-1.5 um.
It should be noted that the step of opening the hole may be before the color filter substrate 120 is attached to the display substrate 130, or after the color filter substrate 120 is attached to the display substrate 130, where the step of opening the hole is before the color filter substrate 120 is attached to the display substrate 130, the requirement on the attachment precision between the color filter substrate 120 and the display substrate 130 is higher, and the requirement on the display panel manufacturing process is invisibly improved, and the step of opening the hole is after the color filter substrate 120 is attached to the display substrate 130, so that the problem of misalignment between the color filter substrate 120 and the display substrate 130 is avoided, and the manufacturing efficiency of the display panel can be improved. Therefore, in this embodiment, it is preferable to open the opening region B after the color filter substrate 120 and the display substrate 130 are bonded.
Specifically, the opening may be achieved by laser integrated cutting, and the cover plate 110 is attached after laser cutting as shown in fig. 4, that is, as shown in fig. 2.

The manufacturing precision of each light shielding layer can be improved by manufacturing each light shielding layer through the yellow light process, and the manufacturing yield of the display panel is further improved.
Further, the cover plate 110 includes a cover plate body 111 and a light shielding member 112 disposed inside the cover plate body 111, and an orthographic projection of the light shielding member 112 on the substrate base plate coincides with an orthographic projection of the channel C on the substrate base plate.
In this embodiment, the front camera 200 is disposed in the opening region B, but the front camera 200 is not in seamless fit with the channel C, and a gap exists between the front camera 200 and the sidewall of the channel C, so that light leaking from the gap between the sidewall of the channel C and the front camera 200 can be shielded by the light shielding member 112, and a user cannot perceive the existence of light leakage, thereby improving the visual sensation of the user.
The light shielding member 112 may be a black matrix.
The embodiment of the invention also provides a display device which comprises the display panel.
The display device may be a display, a mobile phone, a tablet computer, a television, a wearable electronic device, a navigation display device, etc.
