In this case, as shown in FIG. 1A, the edges in the four directions may be rounded, or as shown in FIG. 1B, only the edges in the left and right two directions may be rounded.

The length r of the arc of the curved surface 120a may be exemplified by 2 to 3 mm, preferably 2.5 mm.

And when the length of the touch panel diagonal is 101.6 ~ 254mm, it can be exemplified that the thickness (t) is formed of 3 ~ 7mm.

The body 10 may be made of plastic or glass of a transparent material. In the case of plastics, the manufacturing process is simple and inexpensive, and in the case of glass, transparency and clarity are excellent, and smooth and luxurious surfaces can be formed. Therefore, the material of the touch panel protective cover of the present invention is determined according to various conditions, but considering the surface hardness and transparency, it is preferable to process with glass.

When the material of the touch panel protective cover according to the present invention is glass, the manufacturing method thereof will be described.

6 is a view showing a manufacturing process of the touch panel protective cover according to the present invention, the manufacturing process of the touch panel protective cover as shown is a chamfering process (a) for cutting the edge of the glass, the curved surface chamfered It consists of the rounding process process (b) which makes it into a process, the process (c) which bends glass in order to make an upper surface concave, and the process (d), (e) which processes a lower surface along a cutting line.

In particular, in order to form the upper surface 11 of the body 10 to be concave, the glass is bent in one direction as in the step (c), so that the concave can be easily formed to be symmetrical with respect to the longitudinal center line X.

On the other hand, Figure 7 is a front view showing another embodiment of the touch panel protective cover according to the present invention, Figures 8a and 8b is a view showing a cross section in the longitudinal and transverse direction of the touch panel protective cover of Figure 7, respectively.

As shown in Figure 7 to 8b, the body may be formed concave to be symmetrical with respect to the horizontal center line (Y).

As such, the round portions 120 and 120b of the body of the touch panel protective cover are processed into curved surfaces, and the recessed portions 110 are formed in the central region corresponding to the screen portion 21. By separating the 110, the grip and touch feeling when the user grabs the mobile phone is improved.

Then, the concave portion formed on the upper surface 11 of the body 10 is formed to be concave based on the horizontal center line Y (see FIG. 8A), and is configured to be flat without any inclination at any point in the vertical direction (FIG. 8B). Can be used).

9 is a cross-sectional view showing an embodiment of a touch panel according to the present invention. As shown in FIG. 9, the touch panel 20 according to the present invention includes a substrate 201; An ITO coating layer 202 disposed on the substrate 201 and including an electrode; A first protective layer 203 disposed above the ITO coating layer 202 and having a flat upper surface and a screen portion formed in the center thereof; And a second protective layer 10c attached to the first protective layer 203.

In addition, the lower surface of the second protective layer 10c may be flat, and the upper surface may be configured such that the concave portion 110c and the round 120c portion corresponding to the screen portion are formed.

In this way, the touch panel is manufactured by dividing the first protective layer 203 having a flat upper surface and the second protective layer 10c stacked on the first protective layer 203 and having a central region concave. And while using the manufacturing process of the existing flat touch panel as it is, by adding only the process of attaching the second protective layer on the first protective layer it is possible to manufacture a touch panel that can have a three-dimensional surface and improved grip.
