摘要： A light-emitting device (10) includes a first light-emitting region (100) and a second light-emitting region (200). The first light-emitting region (100) emits a light ray having a first color by making a first light-emitting layer group including at least two or more kinds of light-emitting layers emit light. In addition, the second light-emitting region (200) emits a light ray having the first color (for example, daylight color, natural white color, white color, warm white color, or incandescent color) by making a second light-emitting layer group including at least two or more kinds of light-emitting layers emit light. In addition, at least one kind of light-emitting layer included in the second light-emitting layer group emits a light ray having a different spectrum peak from all of the light-emitting layers included in the first light-emitting layer group. Therefore, the color-rendering properties of light emitted from the light-emitting device (10) are improved.

摘要： 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).
