The transmissive portion 120 shields the transmission of the light emitted from the light source portion 110 except for the transmissive portion 130, and only the transmissive portion 130 can transmit light having a predetermined wavelength.

3 and 4 show an example of a case in which a transmission shape 130 corresponding to the D-stage, which is one of the speed change stages, is formed in the transmission portion 120, A D-stage having the same shape as the shape 130 can be displayed.

In the embodiment of the present invention, since the transmissive portion 120 is formed of a transmissive film, it can have a planar shape as well as a curved shape, thereby improving the degree of freedom of design. In order to display various shapes such as characters or symbols, Since a display device (e.g., LCD, etc.) is not used, the overall configuration can be simplified and the space required for installation can be reduced.

In the embodiment of the present invention, the light emitted from the light source unit 110 directly reaches the transmission unit 120. However, this is merely an example for facilitating understanding of the present invention, A light guide or a diffusion member made of a material having a different diffusing property may be additionally disposed between the light source unit 110 and the transmissive unit 120 so as to increase the transmittance of the color from the light source unit 110 to the transmissive unit 120 .

As shown in FIG. 5, the transmissive portion 120 may have a letter-shaped transmissive shape 131a corresponding to the speed change stage, or a symbol-like transmissive shape 131b such as an emblem of a vehicle may be formed. 5 and 6, transmissive features 131a and symbolic transmissive features 131b are formed. However, the transmissive features 131a and 131b shown in FIGS. 5 and 6 are not limited to the transmissive features 131a and 131b shown in FIGS. And may be formed together in one transmitting portion 120 as well. In the embodiment of the present invention, a plurality of transmission shapes 131a and 131b are formed in one transmission part 120. However, the present invention is not limited to this, (120) may be stacked.

As described above, in the embodiment of the present invention, a plurality of transmission shapes 131a and 131b having different shapes are formed in the transmission portion 120, and light having a wavelength capable of being transmitted by the transmission shapes 131a and 131b is irradiated So that a specific transmission shape can be displayed.

For example, when the transmissive shape 131a of FIG. 5 transmits the red light, the transmissive shape 131b of FIG. 6 transmits the blue light, and when the red light is irradiated from the light source 110 The transmissive shape 131a as shown in FIG. 5 is displayed, and when the blue light is irradiated from the light source 110, the transmissive shape 131b as shown in FIG. 6 can be displayed.

7, when the plurality of transmissive shapes 131a and 131b are formed together in one transmissive portion 120, the red light and the blue light described above are transmitted through the overlapping portions 131c, The respective transmission shapes can be displayed even when the transmission shapes 131a and 131b of the transmission part 120 are formed together.

In the embodiment of the present invention, different transmission shapes, that is, characters and symbol shapes, are displayed by way of example, but the present invention is not limited thereto. It may indicate whether or not to select.

For example, as shown in FIGS. 8 and 9, the transmission shapes 132a and 132b having the same letter shape but different sizes are formed in one transmission part 120 as shown in FIG. 10, and each transmission shape 132a And 132b, it is possible to display whether or not the speed change stage is selected.

In FIG. 10, the portion 132c where the transmission shapes 132a and 132b are overlapped with each other can transmit all the light having the wavelength corresponding to the transmission shapes 132a and 132b to form one transmission portion 120 So that various shapes can be displayed.

The case where the selection of the speed change stage is displayed through the transmissive portion 120 of FIGS. 8 to 10 is shown in FIGS. 11 and 12. FIG. 11 and 12 illustrate an example in which a plurality of transmission shapes are formed together in one transmitting portion 120 as shown in FIG. 10 described above.
