LIGHT-EMITTING DEVICE

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.

1. A light-emitting device comprising:
a first light-emitting region including a first light-emitting layer group constituted of multiple kinds of light-emitting layers emitting light rays having mutually different spectrum peaks; and a second light-emitting region including a second light-emitting layer group constituted of multiple kinds of light-emitting layers emitting light rays having mutually different spectrum peaks, the first light-emitting region adjacent to the second light-emitting region on a common substrate. wherein at least one kind of light-emitting layer in the second light-emitting layer group emits a light ray having a different spectrum peak from all of the light-emitting layers in the first light-emitting group, the first light-emitting region emits a first light ray having a first color by making the first light-emitting layer groups emit light, and the second light-emitting region emits a second light ray having the first color by making the second light-emitting layer groups emit light.
