In the manufacturing method of the display device in this embodiment, the first polarizer and the second polarizer are spliced and attached to the surface of one side of the display panel, and the limitation of the size of the polarizer material to the large-size display device is broken through by splicing the polarizers. And in the splicing region P of the first polaroid and the second polaroid, the part of the second polaroid is overlapped on the first polaroid to form an overlapping part. And cutting the overlapped part of the splicing area according to a first preset cutting length. The size of the required splicing seam can be adjusted and even seamless splicing can be realized by cutting the overlapped part of the first polaroid and the second polaroid by the first preset cutting length.

Referring to fig. 2, in step S1, a display panel 100 is provided.
Specifically, the display panel 100 may be a liquid crystal display panel 100, or may be an Organic Light Emitting Diode (OLED) display panel 100. The display panel 100 is not limited herein.
Subsequently, the process proceeds to step S2.
Referring to fig. 3 to 5, in step S2, the first polarizer 10 and the second polarizer 20 are spliced and attached to one side surface of the display panel 100, and the first polarizer 10 is located on one side of the second polarizer 20. In the splicing region P of the first polarizer 10 and the second polarizer 20, a portion of the second polarizer 20 is overlapped on the first polarizer 10 to form an overlapping portion C.
It is understood that the second polarizer 20 is partially overlapped on the first polarizer 10 to form an overlapping portion C, which facilitates adjustment of the splicing gap between the first polarizer 10 and the second polarizer 20.
Specifically, step S2 includes the steps of:
referring to fig. 3, the step of forming the first polarizer 10 includes the following steps:
step S21, providing a polarizer material, wherein the polarizer material comprises a first release layer L1, a first polarizing layer P1, a first adhesive layer J1 and a second release layer L2 which are sequentially stacked.

Alternatively, the first adhesive layer J1 is made of a pressure-sensitive adhesive, the first compensation layer is made of a Cyclic Olefin Polymer (COP), a cellulose Triacetate (TCA), or the like, such as a COP material having a trade name of SANUQI, a TCA material having a trade name of PK3 and NR01, respectively, and the first protection layer is made of a cellulose Triacetate (TCA) material, such as a triacetate cellulose film (TAC).
Step S22, cutting the second release layer L2 according to a second preset cutting length, so that the second release layer L2 is separated into two parts, wherein the second preset cutting length is greater than the first preset cutting length.
It should be noted that the first preset cutting length is a preset length for cutting the overlapped part C, and is explained in detail below (step S3).
Alternatively, for example, the second predetermined cutting length is greater than or equal to 15 mm, i.e. the second predetermined cutting length is greater than the width of the overlapping portion C. Alternatively, the second preset cut length may be 15 mm, 20 mm, 25 mm, etc.
It can be understood that the second preset cutting length is greater than the width of the overlapping portion C, so that the second release layer L2 of the splicing region P is greater than the width of the overlapping portion C, the first glue layer J1 of the overlapping portion C is not exposed and attached, the overlapping portion C of the splicing region P is conveniently cut and adjusted, and the subsequent tearing and attaching are performed.

The distance between the edge of the third blade D21 and the edge of the fourth blade D22 is the thickness of the polarizer material excluding the second release layer L2. It can be understood that the distances between the knife edges of the third and fourth knife edges D21 and D22 are set such that the outline of the first polarizer 10 is cut completely and the second release layer L2 is effectively separated into two parts when the polarizer material is cut.
In step S222, the polarizer material is cut by the third blade D21 to form the outline of the first polarizer 10. And cutting the second release layer L2 by using a fourth blade D22 according to a second preset cutting length, so that the second release layer L2 is separated into a first part1 and a second part2 to form the first polarizer 10.
The length of the first part1 is greater than the length of the second part 2.
The third cutting edge D21 cuts all film layers of the polarizer material to form the outline of the first polarizer 10, the fourth cutting edge D22 cuts the second release layer L2 of the part of the first polarizer 10 for splicing, and the second release layer L2 is separated into a first part1 and a second part2, so that the first glue layers J1 of different parts of the first polarizer 10 are exposed conveniently, and the subsequent splicing and attaching of the first polarizer 10 are facilitated.
Alternatively, the third and fourth cutting edges D21 and D22 of the second double-edged tool D20 are fixedly connected, or the third and fourth cutting edges D21 and D22 are relatively movable.
One side of the second release layer L2 of the polarizer material is placed upward, and the second double-edge cutter D20 is pressed downward for cutting. When the third blade D21 and the fourth blade D22 are fixedly connected, the third blade D21 can cut the polarizer material simultaneously with the fourth blade D22 cutting the second release layer L2, so that the steps of forming the first polarizer 10 are reduced, and the process is simplified. When the third blade D21 and the fourth blade D22 can move relatively, the third blade D21 cuts the polarizer material first, and the fourth blade D22 cuts the second release layer L2, or the fourth blade D22 cuts the second release layer L2 first, and the third blade D21 cuts the polarizer material again. The cut first polarizer 10 includes a second release layer L2 separated into a first part1 and a second part 2.
Alternatively, the third blade D21 may be a square blade, the fourth blade D22 may be a straight blade or a square blade, and the side length of the square blade of the third blade D21 is greater than that of the fourth blade D22. It is understood that the third cutting edge D21 cuts the polarizer material with a square cutting edge, and the profile of the first polarizer 10 is formed to facilitate splicing with the second polarizer 20.
Referring to fig. 3, the step of forming the second polarizer 20 includes:
in step S23, a polarizer is provided. The polarizer material comprises a third release layer L3, a second polarizing layer P2, a second adhesive layer J2 and a fourth release layer L4 which are sequentially stacked.
Step S24, cutting the fourth release layer L4 according to a third preset cutting length, so that the fourth release layer L4 is separated into a third part3 and a fourth part4, so as to form the second polarizer 20. The length of the third part3 is greater than the length of the fourth part 4. Wherein the third predetermined cutting length is greater than the first predetermined cutting length.
Optionally, the third predetermined cutting length is greater than 15 mm, i.e. the third predetermined cutting length is greater than the width of the overlapping portion C.
The second double-blade tool D20 forming the first polarizer 10 may be used to form the second polarizer 20. The method, principle and function of each step for forming the second polarizer 20 may be referred to the method, principle and function of each step for forming the first polarizer 10, and will not be described herein again.
It should be noted that the steps of forming the first polarizer 10 and the second polarizer 20 are not described in sequence.
Subsequently, the process proceeds to step S25 and step S26 in this order.
Referring to fig. 4, the splicing and attaching of the first polarizer 10 and the second polarizer 20 on one surface of the display panel 100 includes the following steps:
step S25, the first part1 of the second release layer L2 is torn off, and the side of the first polarizer 10 exposed by the first adhesive layer J1 is attached to the display panel 100.
Specifically, the first part1 of the second release layer L2 is removed, and the main body of the first polarizer 10 corresponding to the first part1 is attached and fixed to the display panel 100.
Step S26, tearing off the third part3 of the fourth release layer L4, and attaching the side of the second polarizer 20 exposed by the second adhesive layer J2 to the display panel 100. In the splicing region P, the second polarizer 20 having the fourth part4 is laminated on the first polarizer 10 having the second part 2.
The third part3 of the fourth release layer L4 is removed, and the main body of the second polarizer 20 corresponding to the third part3 is attached and fixed to the display panel 100. In the splicing region P, the second polarizer 20 corresponding to the fourth part4 is not attached to the first polarizer 10 stacked thereon, and the first polarizer 10 corresponding to the second part2 is not attached to the display panel 100 therebelow. The second is from the subsection of type layer L2 and fourth type layer L4 and is torn, the subsection of first polaroid 10 and second polaroid 20 is laminated for on the main part of first polaroid 10 and second polaroid 20 is fixed in display panel 100, the concatenation part can conveniently range upon range of, cut, tear and attach, be unlikely to attached together and influence the secondary cutting, the extrusion piles up the unevenness that causes the rete.

Alternatively, in the present embodiment, the distance that the cutting edge of the first cutting edge D11 is lower than the cutting edge of the second cutting edge D12 is less than or equal to the thickness of the polarizer material excluding the first release layer L1 and the second release layer L2. The distance between the knife point of the first knife edge D11 and the knife point of the second knife edge D12 is greater than the thickness of the first release layer L1/the second release layer L2.
It can be understood that the arrangement of the knife edge distances of the first knife edge D11 and the second knife edge D12 can ensure that the films of the first polarizer 10 except for the second release layer L2 and the films of the second polarizer 20 except for the fourth release layer L4 of the overlapped portion C are completely cut.
