LIGHT DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/173825
Kind Code:
A1
Abstract:
This light device (30) is provided with a light emitting device (10) and a sensor device (20) (a light-receiving element (220)). The light emitting device (10) is provided with a plurality of light emitting units (172) and light transmitting units (174). Each light emitting unit (172) comprises a semi-transmissive reflective layer (140), a first electrode (110), an organic layer (120) and a second electrode (130). Each light transmitting unit (174) comprises a semi-transmissive reflective layer (140) and an organic layer (120) that serves as an optical layer. The number of layers interposed between the semi-transmissive reflective layer (140) and the second electrode (130) of each light emitting unit (172) is larger than the number of layers contained in the organic layer (120) that serves as an optical layer. In addition, the film thickness from the semi-transmissive reflective layer (140) to the second electrode (130) of each light emitting unit (172) is different from the film thickness of the organic layer (120) that serves as an optical layer.
