The decoration film <NUM> according to an embodiment includes an adhesive layer <NUM>, a first decoration layer <NUM>, and a second decoration layer <NUM>.

The adhesive layer <NUM> according to an embodiment may be combined with an inner surface of the front plate or rear plate of the electronic device. The inner surface of the front plate or rear plate may refer to a surface facing an inner space in which various components of the electronic device are disposed. The adhesive layer <NUM> may be formed of, for example, a pressure sensitive adhesive (PSA) or an optical clear adhesive (OCA). The adhesive layer <NUM> may include a processible layer (e.g., a primer layer).

The first decoration layer <NUM> according to an embodiment includes a first shape-cured layer <NUM> and a first color layer <NUM>.

The first shape-cured layer <NUM> according to an embodiment may be formed by applying a polymer resin in a fluid state to a mold having a first three-dimensional pattern and then curing the applied polymer resin by an external stimulus such as ultraviolet rays. For example, the first shape-cured layer <NUM> may be formed using a polymer resin composition of acrylic, urethane, or silicone. The first shape-cured layer <NUM> is combined with the adhesive layer <NUM>. The first shape-cured layer <NUM> may have the first three-dimensional pattern distributed over the entire or partial area of the front plate or rear plate. The first shape-cured layer <NUM> may reflect light in various directions through the first three-dimensional pattern to offer variations in a pattern recognizable to the user. For example, the first three-dimensional pattern may be composed of linear zones repeatedly arranged and gradually changing in size from one end to the other end as shown in <FIG> or from a central portion to both ends as shown in <FIG>. Alternatively, as shown in <FIG>, the first three-dimensional pattern may be composed of many circles or polygons repeatedly arranged and gradually changed in size. Alternatively, as shown in <FIG>, the first three-dimensional pattern may be composed of a plurality of repeated pyramid-shaped regions.

The first color layer <NUM> according to an embodiment may be formed on the first shape-cured layer <NUM> in various colors. The first color layer <NUM> may be formed through deposition of a metal or an oxide. For example, depositing a metal such as indium or an oxide such as titanium oxide, silicon oxide, or aluminum oxide on the first shape-cured layer <NUM> may result in forming the first color layer <NUM> having a specific color.

The second decoration layer <NUM> according to an embodiment includes a second shape-cured layer <NUM> and a second color layer <NUM>.

The second shape-cured layer <NUM> according to an embodiment may be formed by applying a polymer resin in a fluid state to a mold having a second three-dimensional pattern and then curing the applied polymer resin by an external stimulus such as ultraviolet rays. Curing process may be performed simultaneously for the first and second shape-cured layers <NUM> and <NUM>. The second shape-cured layer <NUM> may be combined with the first color layer <NUM>. Like the first shape-cured layer <NUM>, the second shape-cured layer <NUM> may have the second three-dimensional pattern distributed over the entire or partial area of the front plate or rear plate. The second shape-cured layer <NUM> may reflect light in various directions through the second three-dimensional pattern to offer variations in a pattern recognizable to the user. Like the first three-dimensional pattern, the second three-dimensional pattern may be formed of various patterns as shown in <FIG>.

The second color layer <NUM> according to an embodiment may be formed on the second shape-cured layer <NUM> in various colors. Like the first color layer <NUM>, the second color layer <NUM> as well may be formed through deposition of a metal or an oxide. For example, depositing a metal such as indium or an oxide such as titanium oxide, silicon oxide, or aluminum oxide on the second shape-cured layer <NUM> may result in forming the second color layer <NUM> having a specific color.

The first three-dimensional pattern and the second three-dimensional pattern may be identical or similar to each other as shown in <FIG>, but according to the presently claimed invention they are different from each other as shown/illustrated in <FIG>. In addition, the first color layer <NUM> and the second color layer <NUM> may be formed in identical or similar colors or in completely different colors.

When the first and second three-dimensional patterns are identical or similar to each other, the shape of the corresponding pattern may be realized clearer and remarkably. When the first and second three-dimensional patterns are different from each other, a combination of both patterns may create a new three-dimensional pattern. In <FIG>, the first and second three-dimensional patterns are illustrated simply with focus on being different. However, a great variety of combinations in different patterns may be used as shown in <FIG>.

When the first color layer <NUM> and the second color layer <NUM> are formed in identical or similar colors, the color(s) may be realized clearer and remarkably by the second shape-cured layer <NUM> interposed between the first and second color layers <NUM> and <NUM>. When the first color layer <NUM> and the second color layer <NUM> are formed in different colors, the first color, the second color, or any new color resulting from a combination of the first and second colors may be seen to the user, depending on a direction viewed by the user.

Meanwhile, according an embodiment, the decoration film <NUM> may further include a surface treatment layer <NUM> interposed between the first color layer <NUM> of the first decoration layer <NUM> and the second shape-cured layer <NUM> of the second decoration layer <NUM>. The surface treatment layer <NUM> improves the binding strength between the first and second decoration layers <NUM> and <NUM> and may be formed by processing a surface of any one of the first color layer <NUM> or the second shape-cured layer <NUM>. To improve the binding strength, a treatment for increasing the surface energy through, for example, a plasma treatment or an etching treatment may be performed.

In addition, according an embodiment, the decoration film <NUM> may further include a shielding printed layer <NUM> formed on the second color layer <NUM>. The shielding printed layer <NUM> may not only provide a flat surface onto an uneven surface of the second shape-cured layer <NUM>, but also block various components inside the electronic device from being viewed outside.
