The present invention relates to an apparatus for attaching a polarizing film, and more particularly, to prevent breakage of a substrate module in a work process of attaching the polarizing film to a substrate module for a flat panel display device and to prevent the position or posture of the substrate module from changing. It relates to a polarizing film attachment device that can be.

In general, a substrate module of a flat panel display device such as an LCD is manufactured by integrating two substrates facing each other and then forming a polarizing layer on the substrate surface.

The operation of forming the polarizing layer, a method of attaching a conventional polarized film (polarized-film) to the substrate module using a polarizing film attachment device is known.

As such an apparatus for attaching the polarizing film to the substrate module side, there is a polarizing film bonding apparatus of Patent Registration No. 10-0589044 registered and patented on March 10, 2004 by the present applicant.

The loading posture or position of the substrate module can be easily changed by the pressure.

In particular, the phenomenon that the loading posture or the position of the substrate module changes during the attaching operation of the polarizing film may occur more seriously when the attaching the end surface attaching the polarizing film to either side of the both sides of the substrate module. have.
