  • Patent number: 11914246
    Abstract: A display device (1) includes a light-emitting device (10), a reflective liquid crystal element (20), and an optical member (30). The light-emitting device (10) includes a plurality of light-emitting units (142) and a light-transmitting unit (144) located between the light-emitting units (142) adjacent to each other. The light-emitting device (10) is located between the reflective liquid crystal element (20) and the optical member (30). The plurality of light-emitting units (142) emit light toward the reflective liquid crystal element (20). The light emitted from the plurality of light-emitting units (142) is reflected by the reflective liquid crystal element (20), transmitted through the light-emitting unit (142) of the light-emitting device (10), and formed into an image by the optical member (30).

  • Patent number: 11108002
    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 (TR1) (a first light emitting portion (160a)), a second light transmitting region (TR2) (a second light emitting portion (160b)) and a third light transmitting region (TR3) (a first light transmitting portion (162)), more specifically, when light from a D65 light source is transmitted through the first light transmitting region (TR1), the second light transmitting region (TR2) and the third light transmitting region (TR3), both of a color difference between the first light transmitting region (TR1) and the third light transmitting region (TR3) and a color difference between the second light transmitting region (TR2) and the third light transmitting region (TR3) 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 (TR1) and the second light transmitting region (TR2).
