The second substrate 300 may be a color film substrate, the first light-shielding structure 210 is a black color resistor, and the Black Matrix (BM) of the display region 110 and the black color resistor may be formed in the same process. The first substrate 200 may be an array substrate, and the second light shielding structure 310 is a metal trace, such as a fan-out line or other peripheral trace; may be formed in the same process as the scan lines, data lines, common electrode lines, etc. of the display region 110 of the display panel 100, and located in the same metal layer; of course, the second light shielding structure 310 may be a black color mask (BM), and the Black Matrix (BM) of the display region 110 may be formed in the same process.

In an embodiment, the mesh light-shielding body 216 of the first substrate 200 includes a plurality of first stems 211 and a plurality of second stems 212, the first stems 211 and the second stems 212 are perpendicular to each other, and the hollow holes 213 are formed in the regions surrounded by the two adjacent first stems 211 and the two adjacent second stems 212. In this embodiment, the first stem 211 and the second stem 212 are perpendicular to each other, so that the first light shielding structure 210 is a regular mesh, and conforms to the conventional shape of the display panel 100, forming a regular mesh structure.
In one embodiment, the width of the first stems 211 is X, wherein X is less than or equal to 3 micrometers and less than or equal to 30 micrometers. In the scheme, the width of the first trunk 211 is set in the size range of X being more than or equal to 3 microns and less than or equal to 30 microns, so that the first trunk is not too narrow and is easy to break and misplace, and light leakage is avoided; the light-transmitting part is not reduced due to the excessive width; and also ensures the positions of the common electrode lines and the signal lines on the first trunk 211.
In one embodiment, the width of the second stems 212 is Y, wherein Y is less than or equal to 3 micrometers and less than or equal to 30 micrometers. In the scheme, the width of the second trunk 212 is set in the size range of Y being more than or equal to 3 microns and less than or equal to 30 microns, so that the second trunk is not too narrow and is easy to break and misplace, and light leakage is avoided; the light-transmitting part is not reduced due to the excessive width; and also ensures the positions of the common electrode lines and the signal lines on the second trunk 212.
In one embodiment, the first stem 211 and the second stem 212 have different widths. In this embodiment, the widths of the first trunk 211 and the second trunk 212 are different, and in actual operation, the widths of the first trunk 211 and the second trunk 212 can be flexibly designed and arranged according to the required size of the display panel 100, so as to match the layout of the routing on the display panel 100.
In one embodiment, the hollow holes 213 are rectangular, and the length of the hollow holes 213 is M, wherein M is greater than or equal to 2.5 micrometers and less than or equal to 25 micrometers; the width of the hollow hole 213 is N, wherein N is more than or equal to 2.5 micrometers and less than or equal to 25 micrometers. In the scheme, the length and the width of the hollow hole 213 are within the range that M is more than or equal to 2.5 micrometers and less than or equal to 25 micrometers, so that the hollow hole 213 is not too large, and the phenomenon of light leakage of the display panel 100 is avoided; meanwhile, the size of the hollow hole 213 ensures that the widths of the first trunk 211 and the second trunk 212 are in a proper range.
In an embodiment, each of the sheet-shaped light-shielding bodies 311 and each of the hollow holes 213 have the same shape and the same size. In this scheme, the sheet-shaped light-shielding body 311 just covers the hollow hole 213 of the light leak, so that the purpose of fully irradiating the sealant 400 with ultraviolet light can be achieved, the phenomenon of light leak of the display panel 100 can not be caused, the manufacturing cost of the sheet-shaped light-shielding body 311 can be fully saved, and the manufacturing cost of the display panel 100 can be saved.
In an embodiment, the thickness of the second light shielding structure 310 is equal to the thickness of the first light shielding structure 210. In the scheme, the thicknesses of the first light shielding structure 210 and the second light shielding structure 310 are equal, so that no matter which side of the first substrate 200 and the second substrate 300 is irradiated by ultraviolet light, when the incident angle of the ultraviolet light is large, the shadow areas of the first light shielding structure 210 and the second light shielding structure 310 projected on the frame adhesive 400 are not uniform due to the uneven thicknesses of the first light shielding structure 210 and the second light shielding structure 310, and the situation that a part of the frame adhesive 400 cannot be irradiated by the ultraviolet light is caused; and the thicknesses of the first light shielding structure 210 and the second light shielding structure 310 are the same, so that the design of ultraviolet light irradiation is simpler and more convenient, and the factors to be considered are reduced.
As shown in fig. 7, in an embodiment, the area of the sheet-shaped light-shielding body 311 is larger than the area of the hollow hole 213, in the present embodiment, the area of the sheet-shaped light-shielding body 311 is larger than the area of the hollow hole 213, and after the first substrate 200 and the second substrate 300 are aligned, a portion of the sheet-shaped light-shielding body 311 and the mesh-shaped light-shielding body 216 are overlapped, so as to reserve a portion of the area of the sheet-shaped light-shielding body 311, thereby preventing light leakage of the display panel 100.
The difference value between the widths of the sheet-shaped light shielding body 311 and the hollow hole 213 is 1/5-1/3 of the width of the first trunk 211; the difference between the lengths of the sheet-shaped light-shielding body 311 and the hollow hole 213 is 1/5-1/3 of the width of the second trunk 212. In this embodiment, the length and the width of the sheet-shaped light-shielding body 311 are slightly greater than those of the hollow hole 213 and are 1/5-1/3 of the widths of the first trunk 211 and the second trunk 212, so that the sheet-shaped light-shielding body 311 can completely cover the hollow hole 213, and the sheet-shaped light-shielding body 311 is not too wide or too large while the display panel 100 is opaque, thereby preventing part of the sealant 400 from irradiating ultraviolet light.
For example, it is assumed that the width of the first stem 211 is 30 micrometers, the width of the second stem 212 is 30 micrometers, the width of the sheet-shaped light-shielding body 311 is X, and the length is W; the width of the hollow hole 213 is Y, and the length is V; wherein X-Y is more than or equal to 10 microns; W-V is more than or equal to 10 microns.
The design also considers the consideration of the alignment precision, when the first substrate 200 and the second substrate 300 are aligned, the alignment precision in the first direction is set as theta, the alignment precision in the second direction is set as delta, wherein X-Y is more than or equal to 2 theta; W-V is more than or equal to 2 delta.
