The thin film transistor glass 2 and/or the color filter glass 1 include edges or corners formed by laser cutting, and on the edges of the edges or corners, there are provided with the purpose of blocking the laser light from entering the terminal panel. Internal barrier structure.

In the terminal panel of the embodiment of the present invention, the blocking structure 5 in the thin film transistor glass 2 will block the laser light entering the terminal panel through the surface glass when the thin film transistor glass 2 is laser cut, so that it cannot continue to enter the interior; the color filter film The blocking structure 4 in the glass 1 will block the laser light entering the terminal panel through the surface glass when the color filter glass 1 is laser cut, so that it cannot continue to enter the interior. In this way, it is possible to avoid damage to the transistors, signal lines, etc. inside the panel after the laser enters the interior of the terminal panel.

Optionally, the blocking structure is arranged along the laser cutting path; or

The blocking structure is arranged at the start point and the end point of the laser cutting path.

Here, by knowing the set laser cutting path, the blocking structure can be set along the laser cutting path, or only at the start point and the end point of the laser cutting path, so as to block the laser light.

As shown in FIG. 3, in the terminal panel according to the embodiment of the present invention, the thin film transistor glass 2 mainly includes a first glass layer 201, a first metal layer 202, a buffer layer 203, a polysilicon layer 204, and a second insulating layer 205 (including a gate oxide layer 205). Silicon insulating (GI_SiOx) layer 2051 and gate silicon nitride insulating (GI_SiNx) layer 2052), gate molybdenum layer 206, first insulating layer 207 (including interlayer silicon nitride insulating (ILD_SiNx) layer 2071 and interlayer silicon oxide) Insulation (ILD_SiOx) layer 2072), source-drain titanium aluminum titanium metal layer 208, first planarization (PLN) layer 209, common electrode ITO1 layer, third insulating layer 210, pixel electrode ITO2 layer and alignment (PI) layer 211. The first metal layer 202 is a light shielding layer composed of molybdenum metal, the buffer layer 203 is composed of silicon oxide SiOx, the first insulating layer 210 is composed of silicon nitride SiNx, and the ITO1 and ITO2 layers in the frame area are etched away.

In this way, through the first reflective layer 212 between the first glass layer 201 and the buffer layer 203, since the first reflective layer 212 is disposed corresponding to the laser cutting area, the laser beam that penetrates the first glass layer 201 during the cutting process can be transmitted. Absorption or reflection of the laser light reduces the probability that the laser light continues to enter the interior of the terminal panel.

Of course, the first reflective layer 212 can also be disposed between other two layers, such as between the areas where the buffer layer 203 and the GI_SiOx layer 2051 are in contact with each other, or between the areas where the GI_SiOx layer 2051 and the ILD_SiNx layer 2071 are in contact with each other, etc., but In this case, the distance between the first reflective layer 212 and the first glass layer 201 is relatively far, and the effect of preventing the laser from continuing to enter the terminal panel is worse than that of the above-mentioned implementation manner.

Wherein, considering the manufacturing process of the thin film transistor glass 2, preferably, the first reflection layer 212 is formed by forming the first metal layer 202 on the first glass layer 201, and then etching the first reflection layer 212 based on the laser cutting area. The first metal layer 202 is obtained.

It should be understood that, in order to obtain the first metal layer 202 as shown in FIG. 3 on the first glass layer 201 , the first metal layer 202 needs to be deposited on the first glass layer 201 and then etched to retain required part. Therefore, in this etching process, the first reflective layer 212 can also be obtained based on the laser cutting area, and there is no need to add a new process flow, which saves costs. The first reflective layer 212 and the first metal layer 202 are made of the same metal, such as molybdenum.

The groove 501 is obtained in sequence when each layer is formed. For example, after the first planarization layer 209 is formed, a first groove is performed to obtain a first groove as deep as the buffer layer 203; For the three insulating layers 210, a second groove is performed on the third insulating layer 210 corresponding to the first groove, and the third insulating layer 210 with a preset thickness is retained on the groove wall; The position of the groove on the layer 210 is grooved for the third time, and the groove wall retains the alignment layer 211 with a preset thickness; finally, when the thin film transistor glass 2 and the color filter glass 1 are bonded by the sealant 3, the sealant 3 is used.

Preferably, the second reflection layer 6011 is obtained by etching the second metal layer 208 after forming the second metal layer 208 on the first insulating layer 207 .

Here, there is no need to add a new process flow for forming the second reflective layer 6011. After digging a groove on the first insulating layer 207, the first insulating layer 207 is used to obtain part of the second metal layer 208 shown in FIG. 6 . During the etching process, the second metal layer 208 in the groove is retained and used as the second reflective layer 6011 in the groove, so as to achieve the purpose of saving cost.

It should also be known that, as shown in FIG. 7 , in the embodiment of the present invention, the blocking structure is a groove 701 in the color filter glass 1 corresponding to the laser cutting area; wherein,

The opening of the groove 701 is located on the second planarization layer 102 and extends toward the second glass layer 101;
