2. Description of the Related Art Generally, with the development of wireless communication technology, mobile phones have become smaller and complicated, and accordingly, not only electrical characteristics but also mechanical characteristics are required to have high reliability. In particular, the failure of a mobile phone caused by a mistake, such as dropping or stepping in use, is regarded as a measure for evaluating the performance of a mobile phone. In view of such a society, LCD module manufacturers, A method of increasing the strength of the mold frame or a method of providing a window panel on the front surface of the LCD panel is proposed.

2. Description of the Related Art Recently, PDAs, mobile communication terminals or navigation systems for automobiles have formed a large market, and these electronic devices mainly include a touch screen or a touch panel switch on an input operation unit.

The input operation unit of the touch screen is usually made of a transparent conductive plastic film. For example, the touch operation screen may include a tempered glass for protecting a liquid crystal display module in which an image is formed, a decoration film printed with a company logo or a button, an indium tin oxide (ITO) Or the like is adhered through OCA (Optical Clear Adhesive) or the like.

FIG. 1 is an exemplary view for explaining a cross-sectional structure of a protective film of a conventional LCD module for a window, which includes a screen printing layer 10, a deposition layer 20 laminated on the upper end of the screen printing layer 10, A UV pattern layer 30 formed over the entire upper end of the layered layer 20; a PET base film 40 laminated on top of the UV pattern layer 30; And a tempered glass 60 adhered to the upper end of the base 40 through the adhesive layer 50. Such a constitution of the conventional invention is disclosed in "Deco film for touch window" and a manufacturing method thereof (Korean Patent Registration No. 10-1277727) of the following Patent Document 1.

The UV pattern layer 30 is designed to have an arbitrary pattern under the ground film 40 for projecting, diffusing and reflecting light. That is, the design is implemented through the UV pattern layer as described above, and OCA and PET film are integrally applied, and its thickness is about 0.125t.

In the case of this conventional invention, the type and thickness of the material deposited on the deposition layer 20 are adjusted by adjusting the color of the entire film (for example, black sapphire, gold platinum, silver titanium, white pearl, etc.) ) And the reflection of light of a specific wavelength band by the refractive index and the thickness of the deposited material are used as the main technical features.

However, as is well known, it is not easy to realize color uniformity because the deposition process as described above requires extremely high processing difficulty, and it is required to adjust the thickness of the deposition layer extremely accurately in order to realize a specific color. The process becomes more difficult. In order to realize a specific color, a plurality of deposition materials of various materials sequentially form at least two to four layers and must be sequentially deposited. Therefore, the thickness of the deposition layer is thickened and the deposition process belonging to the most complicated process is performed. since it must be repeatedly performed in each layer, the process becomes complicated. The problem with this repetitive deposition process becomes even greater when using E-Beam in vacuum to perform the deposition process in particular.

In addition, due to the characteristics of achieving the implementation of colors through deposition, it is only possible to realize a uniform color as a whole, and it is impossible to express a specific pattern having a color difference.
