Here, the reflectivity and transmittance may be set corresponding to the brightness of the light source provided below, and it is preferable that the light of the light source is set to be displayed in preference to the light reflected by the half mirror layer 30 when the light source is lit Do.

That is, the surface of the half mirror layer 30 has a mirror-like luster through some light reflected from the light incident from the upper part in a state in which the lower light source L is turned off. When the lower light source L is turned on, the amount of light emitted from the light source is larger than the amount of light reflected by the external light, so that the shape of the projection unit 22 is changed by the light of the light source L, Can be displayed on the surface.

At this time, the half mirror layer 30 preferably includes the lustrous nanoparticles. The lustrous nanoparticles may be composed of silver, carbon, aluminum, chromium, nickel and alloy particles of silver, carbon, aluminum, chromium and nickel, respectively, and may have different reflectance and transmittance depending on the kind of particles .

In addition, the upper pattern layer 40 may be formed with a relief having a three-dimensional texture on the upper portion of the half mirror layer 30 as the transparent ink is formed by pad printing.

Here, the upper pattern layer 40 may distort light reflected by the half mirror layer 30. That is, external light incident from an upper portion of the light source L is reflected by the half mirror layer 30 and passes through the upper pattern layer 40. In the upper pattern layer 40, Scattered and released.

That is, when the light reflected by the half mirror layer 30 is directly emitted to a region to which the transparent ink is not applied, and when the transparent ink is emitted through the region to which the transparent ink is applied, do.

At this time, in the region where the transparent ink is not applied, the half mirror layer 30 is directly exposed and shows a mirror gloss. In the region where the transparent ink is applied, distortion due to transmission through both layers is reflected and scattered in various directions The three-dimensional texture can be emphasized through light.

Accordingly, when the light source L is turned off, the upper pattern layer 40 forms a boundary with the light reflected by the half mirror layer 30 to the outer periphery of the second pattern with a mirror gloss, The outer light passes through transparent sheer layers and is refracted and scattered, so that the three-dimensional texture is emphasized, so that it can have a luxurious and beautiful appearance.

Since the upper pattern layer 40 is transparently formed on the upper half mirror layer 30, the upper pattern layer 40 may be formed in the first pattern of the lower pattern layer 20 by the light emitted from the light source when the light source L is turned on. May be displayed in preference to the upper pattern layer 40.

At this time, it is preferable that the first pattern and the second pattern are provided differently, and a different pattern can be displayed according to lighting and lighting of the light source L, so that a very luxurious and luxurious appearance can be provided.

Since the upper and lower pattern layers 40 and 20 having different pattern images are provided on the lower and upper portions of the half mirror layer 30 having both light transmittance and reflectivity, The pattern image displayed on the upper half of the half mirror layer 30 can be switched.

In detail, when the quantity of light emitted from the lower light source is small due to the light source being turned off, the three-dimensional texture of the upper pattern layer 40 can be displayed through the external light reflected from the half mirror layer 30, The image corresponding to the first pattern of the lower pattern layer 20 may be displayed through the light of the light source passing through the projection unit 22. [

In other words, the upper pattern layer 40 is displayed through the external light reflected by the half-layer 30 during a sufficient illuminance during the day, and the upper pattern layer 40 is illuminated through the light emitted from the illuminated light source at night. 1 pattern can be displayed, so that a luxurious appearance in which the satisfaction of the consumer is maximized can be provided.

Of course, a cover layer using the clear ink may be formed on the upper portion of the upper pattern layer 40, and the bonding strength between the half mirror layer 30 and the upper pattern layer 40 may be improved, Can be improved.

Accordingly, it is possible to make the product compact by reducing the thickness of the laminate, and the luminance loss of the light source is minimized at a high transmittance, so that the efficiency of the product can be improved.

When the half mirror layer 30 is formed (S40), a transparent ink is printed on the half mirror layer 30 along a predetermined second pattern to form an upper pattern layer 40 (S50) .

At this time, printing of the upper pattern layer 40 may be performed by pad printing in the same manner as the shielding portion 21, and the transparent ink may be made of a colorless transparent or colorless transparent acrylic urethane-based resin.

In this way, the upper pattern layer 40 can be formed in a precise shape without being smudged or crushed by pad printing using the printing pad 1 made of an elastic material, and the upper pattern layer 40 can be formed on the surface of the half mirror layer 30, So that a three-dimensional texture can be expressed.

In addition, the upper pattern layer 40 may be displayed by emphasizing the three-dimensional texture as the external light reflected by the half mirror layer 30 is refracted or scattered and emitted.

Accordingly, the upper pattern layer 40 is formed by a mirror-like luster displayed at a portion where the half mirror layer 30 is directly exposed when the light source L is turned off, a bilayer layer protruding between the mirror luster, And refracted / scattered light creates a mysterious atmosphere to provide a more sophisticated appearance.

When the light source L is turned on, the first pattern of the lower pattern layer 20 due to the light emitted from the light source is preferentially applied to the upper pattern layer 40 through the reflection light of the half mirror layer 30 A different pattern can be displayed depending on whether the light source L is lit or off, so that a very luxurious and luxurious appearance can be provided.

As shown in FIGS. 8 to 9, it is preferable that a flow hole 221a is formed in the lower portion of the shield 221 to connect the projecting portions 222. Here, the flow holes 221a may be formed so as to pass through both ends of the shield 221.

At this time, the clear ink flowing into one projection part 222 may flow through the flow hole 221a to another projection part partitioned by the shield part 221. [ That is, even if a larger amount of clear ink than the other projection parts flows into one projection part, the amount of clear ink filled in each projection part can be uniformly controlled by the flow through the flow holes 221a.

Accordingly, the clear layer formed by the clear ink can be formed more flat, and even if the clear layer is not applied to the upper portion of the shielding portion 221, the amount of ink filled in each projection portion can be adjusted, Can be reduced.

In addition, the clear ink filled in the flow hole 221a forms a transparent semicircular tube in the lower part of the shielding part 221 to guide the incident light toward the projection part, so that the brightness of the product can be increased.

Meanwhile, the flow hole 221a may be formed through a groove-forming projection 2b protruding from the lower surface of the ink groove 2a of the printing plate 2. [

That is, the shielding ink filled in the ink groove 2a has a shape corresponding to the groove-forming projection 2b, concave upward. At this time, when the shielding ink is transferred to the base panel 210 by the printing pad, a flow hole 221a may be formed in the lower surface of the shield 221 attached to the base panel 210.

As described above, the flow hole 221a through which the clear ink flows under the shielding portion 221 can be easily formed by a simple process of forming the groove forming protrusion 2b in the ink groove 2a without complicated processes.

As described above, the present invention is not limited to the above-described embodiments, and variations and modifications may be made by those skilled in the art without departing from the scope of the present invention. And such modifications are within the scope of the present invention.
