In recent years, mobile and IT devices (mobile phones, PDAs, PMPs, notebooks, etc.) are widely used.

Such mobile and IT devices are provided with a display window. In recent years, a touch screen (TSP: Touch Screen Pad) is generally provided to input information directly to the screen using a hand or a pen on the display window.

On the other hand, a window film (or an icon sheet or the like, hereinafter referred to as a "window film ") is provided on the exterior of the mobile and IT device display window in order to vary the design or protect the touch pad. And an IT device display window. The process for attaching the window film to the touch pad is performed to prevent scattering of glass when the display window is broken, to cause defects in the touch pad, and to remove the window film to reproduce the window film. It is essential ...

FIG. 1 is a perspective view showing a conventional window film as an example of an IT device display window, and FIG. 2 is a sectional view showing a conventional window film.

1 and 2, a conventional window film 1 comprises a substrate 2 constituting an appearance of a cell phone display window and a printed layer (design) 3 printed on the edge of the substrate 2, And is attached to the touch pad TSP by the double-sided tape 4. [

However, in the process of attaching the OCA optical clear adhesive 4 to the window film 1, bubbles may be generated on the attachment surfaces of the window film 1 and the double-faced tape 4, , The window film (1) and the double-sided tape (4) are treated as defective.

This is because the window film 1 has an appearance (design) of a display window of a mobile phone. Therefore, when bubbles are generated on the attachment surface of the window film 1 and the double-sided tape 4, It is because there is a problem in seeing.

Particularly, as shown in Fig. 2, the bubble 6 is generated most at the edge portion A of the substrate 2 and the print layer (design) 3 in the lower surface of the window film 1.

Generally, since the thickness of the print layer (design) 3 is approximately 3 to 60 mu m, a step difference is generated in the edge portion A of the print layer (design) 3 and the substrate 2 by the thickness Even if the double-sided tape 4 is adhered and adhered, a certain amount of bubbles 6 are always generated in the edge portion A of the printed layer (design) 3 and the substrate 2.

At present, the amounts of the window film 1 and the double-sided tape 4 which are treated poorly by the bubbles 6 as described above are considerable, which causes a great loss.

Therefore, it is necessary to reduce bubbles generated in the process of attaching the double-sided tape 4 to the lower surface of the window film 1 in order to attach the window film 1 to the touch pad 5.

In particular, in order to improve the appearance of the cellular phone display window, the printing layer (design) 3 may be further vapor-deposited, thereby thickening the printing layer (design) 3, .
