DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only a case where it is directly connected, but also a case where it is indirectly connected with another part in between. Also, when an element is referred to as " comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view illustrating a cover glass according to a first embodiment of the present invention.

1, the cover glass 100 according to the first embodiment of the present invention includes a glass substrate 110, a smog pattern portion 210, a first color layer 510, and a print layer 610 do.

In the present invention, the cover glass may include all kinds of glass substrates including a window glass. The cover glass may cover the entire front or back of the portable terminal, such as a window glass or battery case. The cover glass may be disposed on a part of the front surface of the portable terminal or a part of the rear surface of the portable terminal. At this time, the cover glass can be applied to a camera window, function buttons, various decorations, and the like. When the cover glass is applied as a camera window, the camera window covers the camera module of the portable terminal and exposes the lens of the camera. When the cover glass is applied as a function button, it can be arranged so as to be the surface of the function button. The various decorations may be all glass substrates arranged to have a decorative effect on the appearance of the portable terminal, and may be, for example, surrounding a camera window.

On the other hand, the cover glass may include openings. The opening may expose a camera lens, a function button, a sensor, or the like, but is not limited thereto and may be for all parts capable of providing decorative effects.

In the present invention, the bezel area means not only an edge area on the cover glass, but also a non-transmissive area that performs a pattern or decorating function, or a specific area that displays an edge of a part between cover glasses for functional discrimination.

The glass substrate 110 protects the display panel inside the portable terminal and transmits the screen of the display panel. Wiring (not shown), a speaker (not shown), a camera (not shown), and the like may be disposed in a bezel region (not shown) of the glass substrate 110. The glass substrate 110 can be cut to a predetermined size according to the application to be used, and then the surface can be cleaned and dried. The glass substrate 110 may be a soda lime glass substrate, an alkali-free glass substrate, a tempered glass substrate, or the like, but is not limited thereto. The glass substrate 110 may be made of a transparent resin material such as acryl rather than a glass material.

The smog pattern unit 210 is disposed on one side of the glass substrate 110. The surface of the smog pattern portion 210 is irregular and finely ground. Therefore, the smog pattern unit 210 can be seen to be translucent or to give a soft feeling.

The smog pattern portion 210 can be formed by sandblasting or corrosion. The sandblast is a method in which high-pressure sand is sprayed onto one surface of a glass substrate to form the surface of the glass substrate into fine irregularities. The corrosion may be performed by dipping the glass substrate into the corrosive liquid.

One surface of the glass substrate 110 on which the smog pattern unit 210 is formed is a surface on which a user's finger is touched, and is a surface exposed to the outside when applied to a product. Accordingly, the external light is reflected and refracted by the smog pattern 210, which is a fine uneven surface, to cause irregular reflection, so that a smooth texture can be exhibited.

The first color layer 510 is formed on the other surface of the glass substrate 110. The first color layer 510 may be formed on the pattern portion 410 of the glass substrate 110. The pattern unit 410 may be a part of the other surface of the glass substrate 110, and may be a region having a specific pattern. That is, the pattern unit 410 may be a portion where the first color layer 510 is formed on the other surface of the glass substrate 110. The pattern unit 410 can be formed using a resist film 310 (see FIG. 2) to be described later. In addition, the pattern portion 410 may be formed at an indented angle through etching (see FIG. 4). The first color layer 510 has the same pattern as the pattern portion and is deposited.

The first color layer 510 may be formed by any one of evaporation, printing, spraying, and plating. For example, the first color layer 510 may be a multi-layered thin film, wherein the multi-layered thin film may be formed by stacking at least one of a metal oxide layer and a non-metal oxide layer. Such a multi-layered film can control various wavelengths of incoming light, thereby achieving color.

Unlike the conventional cover glass 10, since the first color layer 510 is provided on the glass substrate 110, OCA in which light incident on the glass substrate 110 is provided on a component of another material, a PET film And the first color layer 510 without going through the UV pattern. Therefore, the cover glass 100 according to the embodiment of the present invention can have a higher transmittance than that of the conventional cover glass 10, and can be made slim.

The print layer 610 may be provided on the other surface of the glass substrate 110 so as to cover the first color layer 510. The print layer 610 may be a black matrix layer printed using black ink. The black ink may contain an inorganic compound such as a metal, a metal oxide, or an organic compound such as a polymer resin. The print layer 610 may form a bezel region (not shown) of the cover glass 100. The print layer 610 shields light emitted from the display panel to display the display panel (not shown) of the cover glass 100, and can reflect external incident light.

The smog pattern portion 210, the first color layer 510, and the print layer 610 described above may be provided in a bezel region (not shown) of the cover glass 100. Therefore, the cover glass 100 according to the first embodiment of the present invention can display a luxurious image due to the soft texture of the smog pattern portion 210 and the pattern of the first color layer 510.

Then, as shown in Fig. 4D, the resist film 310 is completely removed. In the step of removing the resist film 310, the resist film 310 may be peeled off by immersing the glass substrate 110 in an alkali or strong alkali aqueous solution at room temperature or higher (for example, 40 ° C or higher). The alkali or strong alkaline aqueous solution may not react with the first color layer 510. Thus, only the resist film 310 can be peeled off. The resist film 310 is peeled off and the first color layer 510 coated on the resist film 310 is also removed so that the first color layer 510 is formed on the pattern portion 410 on the glass substrate 110. As a result, Only the layer 510 can be left.
