  When the first light source 130 is turned on, as shown in FIG. 4A, the region (A1 and A2) of the first display shape 110 including the overlapping region A1 is colorless or the emission color of the first light source 130. The area A3 of the second display shape 111 excluding the overlapping area A1 is a red light-transmitting area that has a complementary color relationship with the light emission color of the first light source 130. Therefore, the black color is the same as that of the light shielding area A4. Thereby, only the first display shape 110 is lit and displayed in green.

  When the second light source 131 is turned on, the region (A1 and A3) of the second display shape 111 including the overlapping region A1 is colorless or the emission color of the second light source 131, as shown in FIG. The region A2 of the first display shape 110 excluding the overlapping region A1 is a green light-transmitting region that has a complementary color relationship with the light-emitting color of the second light source 131. Therefore, the black color is the same as that of the light shielding area A4. As a result, only the second display shape 111 is lit and displayed in red.

  As described above, according to the display device 101 of the present embodiment, when illuminated with the first light emission color, the second light emission color that is in a complementary color relationship with the first light emission color except for the overlapping region A1. The region A3 of the second display shape 111 thus formed is black, and only the first display shape 110 is lit and displayed. On the other hand, when illuminated with the second luminescent color, the area A2 of the first display shape 110, which is the first luminescent color complementary to the second luminescent color except for the overlapping area A1, is black, and the second Only the display shape 111 is lit and displayed.

Therefore, the region A3 of the second display shape 111 excluding the overlapping region A1 is a red light-transmitting region that has a complementary color relationship with the emission color of the first light source 130, and the light-shielding region A4 includes the first light-transmitting region A3. Since there is the red second light-transmitting layer 122 that has a complementary color relationship with the emission color of the one light source 130, each of the light sources is black. Thereby, only the first display shape 110 is lit and displayed in green.

  When the second light source 131 is turned on, the regions (A1 and A3) of the second display shape 111 including the overlapping region A1 are colorless or the same red light-transmitting region as the emission color of the second light source 131. Therefore, the region A2 of the first display shape 110 excluding the overlapping region A1 is a green light-transmitting region that has a complementary color relationship with the light emission color of the second light source 131, and the light-shielding region A4 includes the first light-transmitting region A2. Since there is the green first light-transmitting layer 121 that is in a complementary color relationship with the light emission color of the two light sources 131, each of them becomes black. As a result, only the second display shape 111 is lit and displayed in red.

  As described above, according to the display device 201 of the present embodiment, when illuminated with the first light emission color, the second light emission color that is in a complementary color relationship with the first light emission color except for the overlapping region A1. The region A3 of the second display shape 111 thus formed is black, and only the first display shape 110 is lit and displayed. On the other hand, when illuminated with the second luminescent color, the area A2 of the first display shape 110, which is the first luminescent color complementary to the second luminescent color except for the overlapping area A1, is black, and the second Only the display shape 111 is lit and displayed. By using the complementary color in this way, the first display shape 110 and the second display shape 111 can be switched and displayed on one display board 202. Accordingly, the configuration of the display device 201 can be simplified, and the display area can be reduced while maintaining the display size of each display shape.

  Further, in the display device 201 of the present embodiment, instead of forming the light shielding layer in the light shielding region A4 of the display plate 202, the first light transmissive layer 121 and the second light transmissive layer 122 are formed to overlap each other.
