The belt 22 is provided, and the suction sheet 22a is constantly attached to the surface of the belt 22 so that the film F supplied from the film supply unit is attached to the surface of the belt 22. It becomes possible. On the other hand, on the track of the belt 22, a protective film peeling unit 28 for removing the protective film F1 attached to one surface of the film F is provided. Therefore, the film F attached to the surface of the belt 22 is displayed through the process in which the pressing roller 26 installed inside the track of the belt 22 is moved toward the path through which the display panel P passes. It adheres to the surface of the panel P.

On the other hand, Figure 3 is a view for explaining the structure of the film attachment device of a conventional stage display panel.

As shown in FIG. 3, in the film attaching device 30 of the conventional stage type display panel, a stage 32 having a flat plate shape is installed on both upper and lower sides, upper and lower sides of a path through which the display panel P passes. A plurality of suction holes 34 penetrate through the stage 32, and a compression roller provided at one end of the stage 32 in a state in which the film F, such as a polarizing film, is widely spread on the stage 32, is adsorbed. The film F is attached to the display panel P by the operation of 36.

However, in the film attaching apparatus of the conventional stage type display panel as shown in FIG. 3, there is a disadvantage in that the film is not supplied in the state where the front end of the film such as the polarizing film is closely adhered to the surface of the stage. .

In addition, in the film attaching apparatus of the conventional stage type display panel, since the stages were difficult to be compatible with the size of the display panel, stages of various standards were required, and a lot of time was required for setting the stage according to the mode change. There was a problem such as being.
