In this embodiment, the decorative panel 10 is suitable for presenting the decorative pattern PT, and the decorative pattern PT corresponds to the light-transmitting structure 150 . In detail, the first area 10a of the decorative panel 10 does not include the light-transmitting structure 150, the second area 10b of the decorative panel 10 includes the light-transmitting insulating structure 150, and the thickness C1 of the cholesteric liquid crystal layer 170 in the first area 10a is greater than that of the second area. The thickness C2 of the cholesteric liquid crystal layer 170 of 10b. When the decorative panel 10 is in the decoration mode, the decorative panel 10 is not enabled and the cholesteric liquid crystal layer 170 is in a reflective state. At this time, the reflectivity of the first area 10a is higher and tends to display the color that the decorative panel 10 wants to reflect. The reflectivity of the second area 10b is lower (that is, the transmittance is higher) and is biased to display the color behind the decorative panel 10. The color of an object (such as, but not limited to: a display panel). Thereby, the decorative panel 10 can present the decorative pattern PT (shown in FIG. 4 ).

For example, in this embodiment, the color that the decorative panel 10 wants to reflect is The color can be red and yellow, which is similar to the color of wood; the object behind the decorative panel 10 is, for example, a black display panel.

It is worth noting that since the first spacer 142 and the second spacer 144 have different heights, the thicknesses C142 and C144 of the cholesteric liquid crystal layer 170 of the decorative panel 10 near the first spacer 142 and the second spacer 144 are different. Since the thicknesses C142 and C144 of the cholesteric liquid crystal layer 170 of the decorative panel 10 near the first spacer 142 and the second spacer 144 are different, the decorative panel 10 reflects a specific color near the first spacer 142 and the second spacer 144 The reflectivity is also different. Thereby, while the decorative pattern PT corresponding to the light-transmitting structure 150 is presented, the color depth of the decorative pattern PT near the first spacer 142 and the second spacer 144 will be different, so that the visual appearance of the decorative pattern PT will be different. The effect is richer.

For example, in this embodiment, the first direction d1 is parallel to an edge 130e of the polymer layer 130, and the first supporter 142 and the second supporter 144 are optional. are arranged in the first direction d1. In this embodiment, the heights of the plurality of supports 140 may increase from left to right. Take this to decorate The right side of the panel 10 reflects a specific color with a higher reflectivity, while the right side of the decorative panel 10 exhibits a darker specific color (for example, deeper red and yellow); the left side of the decorative panel 10 reflects a specific color with low reflectivity, and the decorative panel 10 displays a darker specific color. The left side of panel 10 presents a lighter specific color (for example: lighter red-yellow). In this embodiment, the heights of the plurality of supports 140 can gradually increase from the left to the right, and the color depth of the decorative pattern PT can correspondingly gradually become darker from the left to the right. However, the present invention is not limited thereto. In other embodiments, the color depth of the decorative pattern PT can be changed by changing the height distribution of the plurality of supports 140.
