Abstract
When visible light (light having wavelength of 380 nm or more and 780 nm or less) is transmitted through a first light transmitting region (TR) (a first light emitting portion ()), a second light transmitting region (TR) (a second light emitting portion ()) and a third light transmitting region (TR) (a first light transmitting portion ()), more specifically, when light from a D65 light source is transmitted through the first light transmitting region (TR), the second light transmitting region (TR) and the third light transmitting region (TR), both of a color difference between the first light transmitting region (TR) and the third light transmitting region (TR) and a color difference between the second light transmitting region (TR) and the third light transmitting region (TR) are both, for example, 0.4 or more and 6.5 or less in CIELAB. This reduces conspicuousness of both of the first light transmitting region (TR) and the second light transmitting region (TR). Furthermore, it is possible to identify the first light transmitting region (TR), the second light transmitting region (TR), and the third light transmitting region (TR).
