In this case, it may be difficult for the user to actually recognize the difference in the visual effect due to the light according to the presence or absence of the seventh layer 570 . For example, if there is no difference in refractive index between the first layer 510 and the seventh layer 570 or is less than or equal to a threshold value, it may be difficult to realize a visual effect by the light spectrum by the first interface (①). When the refractive index difference between the second layer 520 and the seventh layer 570 is greater than the refractive index difference between the first layer 510 and the seventh layer 570, the light reflected and/or diffracted at the second interface ② The amount of may be greater than that of the first interface (①), and a visual effect due to the light between the first layer 510 and the second layer 520 may be substantially realized by the second interface (②).

When light is incident on the second surface 110B, the visual effect by the decoration layer 500 may be provided to the user, including the visual color by the seventh layer 570 . In one embodiment, the seventh layer 570 is a layer having a color positioned closest to the second surface 110B of the second plate 111 , and when light is incident on the second surface 110B, the seventh layer 570 is the second surface 110B. 2 It is possible to implement a unique visual color of the plate (111).

According to an embodiment, the material of the third layer 530 and/or the fourth layer 540 may be selected in consideration of a difference in refractive index between the third layer 530 and the fourth layer 540 . For example, as the difference in refractive index between the third layer 530 and the fourth layer 540 is smaller, the reflectance at the fourth interface 4 may be lowered. The lower the reflectance at the fourth interface ④, the less the amount of light reflected and/or diffracted at the fourth interface ④, so the visual texture, visual pattern, or visual color based on the second pattern 541 It may be difficult to implement various characteristics such as

For example, the visual texture or visual pattern by the second pattern 541 may be perceived by the user at a greater distance than the visual texture or visual pattern by the first pattern 521 .

For example, although not shown, when the second pattern 541 is formed on the third interface ③ between the second layer 520 and the third layer 530 , the first pattern 521 and the second Since the separation distance between the patterns 541 is small compared to the embodiment of FIG. 5 , the first visual effect by the first pattern 521 and the second visual effect by the second pattern 541 are different from each other in depth. may be difficult to provide.

In one embodiment, as shown in FIG. 5 , the third layer 530 is disposed between the second layer 520 and the fourth layer 540 , and the second pattern 541 is formed on the third layer 530 . ) and the fourth interface (④) between the fourth layer 540, the first visual effect by the first pattern 521 and the second visual effect by the second pattern 541 have a different sense of depth In addition to being implemented as , a visual color by the third layer 530 may also be implemented. This is in that the third layer 530 can further realize the visual color, so that the thickness of the second layer 520 is increased while forming the second pattern 541 on the third interface ③ to increase the thickness of the first pattern. It may be advantageous over a method of implementing the first visual effect by 521 and the second visual effect by the second pattern 541 with different senses of depth.
