[0025] see figure 2 The polarizer 2 provided by the first embodiment of the present invention is approximately rectangular, and includes a body 21 with a polarizing function, an adhesive layer 22 formed on one surface of the body 21, and a release film covering the surface of the adhesive layer 22 twenty three. The body 21 may include the structure of a conventional polarizer, for example, it may include a polarizing film in the middle, a TAC film on both sides of the polarizing film for protection, and a protective film on one side of the TAC film. When the polarizer 2 is pasted on the display panel, the release film 23 will be torn off from the adhesive layer 22 . see image 3 , is a schematic plan view of the polarizer 2 after the release film 23 is peeled off. The adhesive layer 22 of the polarizer 2 includes a first region of glue 221, a second region of glue 222 and a third region of glue 223 arranged in parallel along the length direction of the surface of the polar...

[0027] The structure of the polarizer (not shown) provided by the second embodiment of the present invention is similar to the polarizer 2 of the first embodiment, the only difference is that in the second embodiment, the viscosity of the first region glue 221 The relationship between p1, the viscosity p2 of the second area glue 222 and the viscosity p3 of the third area glue 223 is: p1<p2, p1<p3. Similarly, for the convenience of manufacture, the second region glue 322 and the third region glue 323 can also be made of the same glue material, that is, p2=p3.

[0029] see Figure 4 The structure of the polarizer 3 provided by the third embodiment of the present invention is similar to that of the polarizer 2 of the first embodiment, the difference lies in the structure of the adhesive layer. The glue layer 32 of the polarizer 3 includes a first region of glue 321 , a second region of glue 322 , a third region of glue 323 , a fourth region of glue 324 and a fifth region of glue 325 arranged in parallel. The first area of ​​glue 321 is located between the second area of ​​glue 322 and the third area of ​​glue 323, and the fourth area of ​​glue 324 is located on the side of the second area of ​​glue 322 away from the first area of ​​glue 321. On one side, the fifth area of ​​glue 325 is located on a side of the third area of ​​glue 323 away from the first area of ​​glue 321 . The viscosity of the glue 321 in the first region is p1, the viscosity of the glue 322 in the second region is p2, the viscosity of the glue 323 in the third regi...

Abstract

The invention provides a polarizer. The polarizer comprises a body with a polarizing function and an adhesive layer formed on the surface of the body. The adhesive layer comprises a number of adhesive regions which are arranged side by side along any dimension direction of the surface of the body. The viscosity of a number of adhesive regions is sequentially increased or decreased from the periphery of the adhesive layer to the central part of the adhesive layer. The invention further provides a display panel including the polarizer and a display including the polarizer.

Description

technical field [0001] The invention relates to a polarizer, a display panel and a display containing the polarizer. Background technique [0002] With the thinning of the display, the thickness of the display panel is continuously reduced. Taking the liquid crystal panel as an example, its thickness has been developed from the mainstream 0.5mm in the past to 0.2mm. The display panel is mostly used in combination with a polarizer, which is an optical element with a multi-layer structure, which is often used in a display and pasted on the display panel to play a polarizing role. see figure 1 The polarizer 1 includes a polarizing film 10 in the middle, a triacetate cellulose (TAC) film 11 that protects both sides of the polarizing film 10, a protective film 12 that is arranged on one side of the TAC film 11, and that is arranged on The adhesive layer 13 on the other side of the TAC film 11 and the release film 14 coated on the adhesive layer 13 . The material of the polariz...
