According to such a configuration, since the light reducing layer is provided on the light-colored layer, light of a specific color corresponding to the light-colored layer is emitted from the light reducing layer side toward the light-colored layer side. When irradiated, the loose color layer develops a specific color strongly and weakly develops colors other than the specific color. Therefore, the specific color can be visually recognized even when the luminance is reduced in the light reducing layer, while the color other than the specific color is difficult to be visually recognized because the luminance is reduced in the light reducing layer.

  In the decorative laminated structure, the play color layer has a plurality of partition portions arranged in an extending direction, and one partition portion of the plurality of partition portions is based on one specific color. The other color portions may be configured to generate a play color effect based on another specific color different from the one specific color. In this way, by changing the wavelength of the light to be irradiated, it is possible to partially cause a play color effect and change the color that is the basis of the play color effect.

  In the decorative laminated structure, the play color layer has a plurality of layer portions arranged in a thickness direction, and one layer portion of the plurality of layer portions has one specific color. The play color effect based on the base tone may be generated, and the other layer portions may be configured to generate the play color effect based on another specific color different from the one specific color. By doing in this way, the color used as the base color of a play color effect can be changed by changing the wavelength of the light to irradiate.

FIG. 4 is a partially enlarged view of the rear surface of the housing of the electronic device of FIG. 1 and shows a state in which blue light is irradiated.

  An electronic device 1 according to the present embodiment illustrated in FIG. 1 is a mobile terminal such as a smartphone. A decorative laminated structure 20 is provided on the surface 11 on the back side of the housing 10 provided in the electronic apparatus 1.

  The housing 10 of the electronic device 1 is formed in a box shape, and the housing 10 accommodates various components such as an electronic component and a printed board for realizing the function of the electronic device 1. The surface 11 on the back side of the housing 10 is colored black. The surface 11 may be colored other than black.

  As shown in FIG. 2, the decorative laminated structure 20 includes a decorative layer 21 provided on the surface 11 of the housing 10, a play color layer 22 provided on the decorative layer 21, A light reducing layer 23 provided on the color layer 22. When the decorative laminated structure 20 is viewed from the light-reducing layer 23 side toward the play-colored layer 22 side, characters, figures, symbols, and the like represented by the surface 11 of the housing 10 and the decorative layer 21 are displayed. The design is visually recognized through the light reducing layer 23 and the play color layer 22.

  The decorative layer 21 is made of, for example, white ink in which titanium dioxide as a pigment is mixed with a binder. The decorative layer 21 is formed by applying white ink to the surface 11 of the housing 10. The decoration layer 21 may be a color other than white, such as red, blue, and yellow. Moreover, the decoration layer 21 may be a film in which a synthetic resin colored in advance is formed.

  As a result, since the light reducing layer 23 is provided on the light-coloring layer 22, the blue wavelength corresponding to the light-coloring layer 22 from the light-reducing layer 23 side toward the light-coloring layer 22 side. When the light is irradiated, the play layer 22 develops a strong blue color and weakly colors other than the blue color. Therefore, the blue color can be visually recognized even when the luminance is reduced by the light reducing layer 23, while the colors other than blue are difficult to be visually recognized because the luminance is reduced by the light reducing layer 23. Therefore, when the light of a specific wavelength is irradiated, the color development other than the specific color corresponding to the light can be suppressed.
