It should be noted that fig. 1 only shows that the first special-shaped boundary 21 in the color filter substrate 100 is in an arc shape, and a boundary opposite to the first special-shaped boundary 21 in the special-shaped non-display area 20 is also in an arc shape, which is not limited in this application, and other shapes besides an arc shape may also be implemented. In addition, fig. 1 also only shows that the color filter substrate 100 includes a plurality of special-shaped non-display regions 20, which are symmetrically distributed at four corners of the color filter substrate 100 under the viewing angle shown in fig. 1, except that in this way, the special-shaped non-display regions 20 may also be disposed at other positions on the color filter substrate 100, which is not specifically limited in this application. In fig. 2, the relative positional relationship among the substrate base 30, the black matrix layer 40, the first color resist layer 51, and the second color resist layer 52 is only schematically illustrated, and does not represent actual dimensions or numbers.

The edge of the shaped non-display area 20 away from the first shaped boundary 21 is typically cut by laser cutting, that is, the edge of the shaped non-display area 20 away from the first shaped boundary 21 is the laser cut edge 23, and with reference to fig. 1, 3 and 4, the area between the laser cut edge 23 and the display area 10 is just the shaped non-display area 20, whereas in the present application, the second black matrix 42 and the second color resist layer 52 are disposed in the shaped non-display area 20, and the second color resist layer 52 is disposed on the side of the second black matrix 42 away from the substrate base plate 30 and is in direct contact with the second black matrix 42. In the laser cutting process, the heat generated at the position of the cutting edge 23 can be led out through the second color resist layer 52 and the second black matrix 42, from the cutting edge 23 to the display area 10, the heat generated by the laser cutting can be dissipated through the second color resist layer 52 and the second black matrix 42 in the diffusion process, so that the phenomenon of overhigh local heat during the laser cutting can be reduced, the reduction of the size of the heat transferred to the display area 10 is facilitated, the influence of the heat generated in the laser cutting process on devices in the display area 10 is facilitated, the display defect problem caused by burn of the special-shaped display panel on the display panel in the laser cutting process is facilitated, and the production yield of the color film substrate 100 is further facilitated to be improved.
Alternatively, referring to fig. 3 and 4, in the display panel provided in the embodiment of the present application, in the special-shaped display area 10, the second color resist layer 52 includes a plurality of opening portions 50, and the opening portions 50 penetrate through the second color resist layer 52 in a direction perpendicular to the substrate base plate 30.
Specifically, with continued reference to fig. 3 and 4, in the present application, the second color resist layer 52 is provided with a plurality of openings 50 penetrating the second color resist layer 52, and the heat generated during the laser cutting along the cut edge 23 is diffused to the second color resist layer 52, and the second color resist layer 52 has thermal conductivity, so that the generated heat can be conducted and dissipated. In this embodiment, a plurality of openings 50 penetrating through the second color resist layer 52 along the direction perpendicular to the substrate 30 are disposed on the second color resist layer 52, in the process of heat conduction, the plurality of openings 50 provide a heat dissipation space with a larger area for heat conduction, so that heat generated by laser cutting can be dissipated not only from the surface and the bottom of the second color resist layer 52, but also from the openings 50, thereby increasing the heat dissipation dimension, facilitating the improvement of the heat dissipation efficiency of heat generated by laser cutting, further reducing the heat conducted to the display area 10, further facilitating the improvement of the display defect problem caused by burn of the display panel in the process of laser cutting of the special-shaped display panel, and further facilitating the improvement of the production yield of the color film substrate 100.
Optionally, fig. 5 is a schematic layout view of the opening portions 50 in the special-shaped non-display area 20 in the color filter substrate 100 provided in this embodiment of the application, where in the special-shaped non-display area 20, the layout density of the opening portions 50 close to the first special-shaped boundary 21 is less than the layout density of the opening portions 50 far from the first special-shaped boundary 21.
It should be noted that fig. 5 only schematically illustrates the arrangement of the opening portions 50, the opening portions 50 in this embodiment are square, the shape of the opening portions 50 is not limited in the present application, and the shape of the opening portions 50 may be other shapes.
Specifically, referring to fig. 5, the present application sets the arrangement density of the opening portions 50, which are disposed through the second color resist layer 52, in the non-uniform arrangement in the shaped non-display area 20, and the closer to the cut edge 23 (i.e., the boundary of the shaped display area 10 opposite to the first shaped boundary 21), the greater the arrangement density of the opening portions 50. Because the heat that produces in the laser cutting process is probably gathering in the position that is close to cutting edge 23, when setting up the density that is close to opening 50 of cutting edge 23 position great, the heat that produces in the laser cutting process will be able to carry out conduction heat dissipation through more openings 50, and this kind of design is favorable more to promoting the radiating efficiency, improves the bad problem of demonstration that special-shaped display panel causes the burn and leads to the fact display panel in the process of laser cutting.

Of course, at least two second color resistors 521 can be formed between the plurality of second color resistors 521 as shown in fig. 8, so that heat generated during the laser cutting process can be conducted and dissipated between the second color resistors 521 connected to each other, and can be dissipated through the surface and the side surface of the second color resistor 521 far away from the substrate, which can also achieve a better heat dissipation effect.
