Therefore, when the polarizing panel 1 is brought into close contact with the lower side of the adhesive panel B, the polarizing panel 1 is adhered to the lower surface of the adhesive panel B by the adhesive force of the adhesive panel B, It is possible to stably transmit the polarizing panel 1 without applying an unnecessary external force to the polarizing panel 1.

On the other hand, since the adhesive panel B has a strong adhesive force, when the entire surface of the polarizing panel 1 is in close contact with the adhesive panel B, the polarizing panel 1 is unnecessarily strongly adhered to the adhesive panel B An excessive external force is applied to the polarizing panel 1 when the polarizing panel 1 adhered to the adhesive panel B is ejected from the adhesive panel B after the polarizing panel 1 is transferred to a desired position The polarizing panel 1 may be damaged.

2 and 3, a concave portion 10 is formed on the side of the adhesive panel B on which the polarizing panel 1 is to be adhered so that the adhesive panel B and the polarizing panel 1) of the contact surface.

The concave portion 10 is recessed by etching the surface of the adhesive panel B and a portion other than the concave portion 10 in the adhesive panel B, The contact area between the adhesive panel B and the polarizing panel 1 is reduced by the area of the recess 10 so that the polarizing panel 1 is suitable for the adhesive panel B Make it stick with force.

At this time, the concave portion 10 is formed in a circular shape having a diameter of about 100 to 300 탆, and a plurality of the concave portions 10 are formed at appropriate intervals on the surface of the adhesive panel B.

When the polarizing panel 1 is repeatedly transferred using the adhesive panel B, the adhesive panel B is charged by static electricity, and the polarizing panel B is charged by using the thus charged adhesive panel B, The polarizing panel 1 is also charged and adversely affects the display panel manufactured using the polarizing panel 1 such as shock.

Accordingly, such a transfer device is provided with various methods or apparatuses for effectively removing the static electricity generated in the pressure-sensitive adhesive panel B. In such a device, the structure is complicated and it is difficult to remove static electricity in real time .

Therefore, in recent years, a method of removing static electricity in real time by mixing a conductive antistatic agent into the adhesive panel (B) when manufacturing such an adhesive panel (B) has been studied.

However, when the adhesive panel (B) is molded by mixing the antistatic agent with the synthetic resin serving as the raw material of the adhesive panel (B), the synthetic resin and the antistatic agent are not uniformly mixed, There is a problem that it is difficult to effectively remove the static electricity generated in the panel B.

This problem has arisen in the same manner as in the above-described polarizing panel 1, but also in all kinds of adhesive panels B used for conveying various kinds of panels, films, tapes and the like.

Therefore, there is a need for a new method to solve such a problem.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 4 to 11 illustrate an adhesive panel according to the present invention, which is used for conveying a polarizing panel.

According to this, the adhesive panel is made of a synthetic resin material having adhesive strength, and the polarizing panel is provided in the transfer device so as to be adhered to the adhesive panel.

According to the present invention, the recessed portion 10 and the flat surface portion 20 are formed on the adhesive surface to which the polarizing panel is adhered in the adhesive panel, and the antistatic agent 30 is applied to the recessed portion 10.

In more detail, the concave portion 10 is formed by concavely etching the adhesive surface of the adhesive panel by a chemical etching method.

The flat portion 20 is formed of a plurality of flat portions 20, and each of the flat portions 20 is formed to protrude in a relief shape while being mutually laterally spaced between the concave portions 10.

To this end, the concave portion 10 includes a plurality of X-axis extending portions 11 spaced apart from each other in parallel, a plurality of Y-axis extending portions 12 parallel to each other and intersecting the X-axis extending portion 11, And each of the planar portions 20 is formed so as to protrude upwardly between the X-axis extending portion 11 and the Y-axis extending portion 12.

The X-axis extending portion 11 and the Y-axis extending portion 12 are recessed to have a triangular or rhombic cross-sectional shape, and the plane portion 20 is a circle having a diameter of about 100 to 200 탆 .

The antistatic agent 30 is formed by mixing a fine conductive powder and an adhesive component in a liquid or gel state and is applied to the recess 10 so as to surround the periphery of the planar portion 20. [

Since a variety of such antistatic agents 30 have been developed and used, the detailed description of the components of the antistatic agent 30 will be omitted.

When the polarizing panel is adhered to the flat portion 20 of the adhesive panel, the polarizing panel is coated with the antistatic agent 30, (30).

A method of applying the antistatic agent 30 such that the top surface of the antistatic agent 30 is located below the flat surface 20 will now be described.

First, as shown in Fig. 9, the surface of the adhesive panel is etched to form a concave portion 10 and a plurality of flat portions 20.

Then, as shown in Fig. 10, a sufficient amount of the antistatic agent 30 is applied to the concave portion 10 by the antistatic agent 30.

At this time, the antistatic agent 30 is sufficiently coated to cover the upper surface of the flat surface portion 20.

Then, as shown in Fig. 11, the antistatic agent 30 on the upper surface of the plane portion 20 is wiped off.
