[0003] see figure 1 , when the full bonding method is used to realize the bonding of the touch panel and the display module, if the display panel in the display module is not strong enough to withstand pressure, when the touch panel is touched, the pressure exerted may be The display substrate in the display panel is deformed, so that the liquid crystal 1 inside the display panel corresponding to the pressure-stressed area diffuses toward the peripheral area of ​​the pressure-stressed area, resulting in an excessive number of liquid crystals 1 in the peripheral area and disordered arrangement, so that the pressure-stressed area and its Optical display differences occur in the surrounding area, resulting in defects such as water ripples on the screen displayed by the liquid crystal display device
In the prior art, such water ripple phenomenon is generally alleviated by increasing the density of the main column spacer 2 inside the display panel and reducing the step difference between the main column spacer 2 and the auxiliary column spacer 3, etc., but in this way It will reduce the area occupied by the liquid crystal 1 in the display panel and increase the difficulty of the production process of the liquid crystal display device

preparation example Construction

[0042] The embodiment of the present invention also provides a preparation method of a polarizer, the preparation method comprising:

[0043] Forming a first protective layer 8, a polarizing layer 9 and a second protective layer 10 stacked in sequence;

[0044] An adhesive layer 11 is superimposed on the side of the second protective layer 10 away from the polarizing layer 9 by a spin-coating process, and elastic particles 12 capable of absorbing pressure are provided in the adhesive layer 11 .

[0045] In the preparation method of the polarizer provided in this embodiment, an adhesive layer 11 is superimposed on the side of the second protective layer 10 away from the polarizing layer 9, and the adhesive layer 11 is provided with elastic particles 12 capable of absorbing pressure; therefore, when When pressure is applied on the polarizer, the elastic particles 12 in the adhesive layer 11 will play a certain buffering effect on the pressure exerted by the outside world, that i...

Embodiment 1

[0051] Step S1: Form the first protective layer 8, the polarizing layer 9 and the second protective layer 10 stacked in sequence; wherein, the polarizing layer 9 can be formed by using conventional materials such as polyvinyl alcohol, and the polarizing layer 9 is used to direct the light passing through it Converted to linearly polarized light in a specific polarization direction, that is, to play a polarizing role; both the first protective layer 8 and the second protective layer 10 can be formed of materials such as triacetate cellulose, and are used to protect the polarizing layer 9 to prevent the polarizing layer 9 from rupture;

[0052] Step S2: Coating silicon dioxide on the side of the first protective layer 8 away from the polarizing layer 9 by using a spraying process;

[0053] Step S3: Coating the adhesive layer material on the side of the second protective layer 10 away from the polarizing layer 9 by using a spin coating process to form the adhesive layer 11; the a...

Abstract

The invention discloses a polarizer, a production method thereof and a liquid crystal display device, relates to the technical field of display, and aims to avoid the ripples of images displayed by a liquid crystal display device. The polarizer comprises a first protecting layer, a polarizing layer, a second protecting layer and an adhering layer which are sequentially stacked, wherein elastic particles capable of absorbing pressure are arranged in the adhering layer. The liquid crystal display device comprises a display panel, an upper polarizer and a lower polarizer, wherein each of the upper polarizer and the lower polarizer is the polarizer mentioned above. The polarizer is used for converting light penetrating the polarizer into linearly polarized light with a specific polarization direction.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a polarizer, a preparation method thereof, and a liquid crystal display device. Background technique [0002] With the continuous development of display technology, liquid crystal display devices with touch function are more and more used in people's life; this liquid crystal display device with touch function is framed or The full-fit method is used to fit the touch panel; the full-fit method refers to the seamless and complete bonding of the display module and the touch panel with water glue or optical glue, so the full-fit method is more conducive to liquid crystal display Devices are thinner and lighter, and their applications are becoming more and more extensive. [0003] see figure 1 , when the full bonding method is used to realize the bonding of the touch panel and the display module, if the display panel in the display module is not strong enough to withstand pressure...
