摘要： A lighting device includes a plurality of organic EL light-emitting devices having organic EL elements, and a plurality of LEDs. The LEDs are provided as point light sources, and the organic EL light-emitting devices are provided as surface light sources. Using an LED which emits blue light and an organic EL element which emits yellow light, white light can be obtained. The LEDs are provided on the back side or the front side of the organic EL light-emitting devices so that light from the LEDs pass between the two organic EL light-emitting devices. Accordingly, light can be extracted from the LEDs without allowing the LED light to pass through the organic EL elements. Further, the organic EL element is sealed by two substrates and a sealant, whereby deterioration due to moisture or oxygen can be prevented.

摘要： Blue organic EL elements, which have a shorter lifetime and lower luminance characteristics than green and red ones, have had a problem: particularly when blue elements are used in a light-emitting device capable of modulating light emission colors, light significantly attenuates and characteristics further deteriorates. A dielectric mirror which is selective in wavelength is provided between organic EL elements, and the number of times especially blue light emission from an organic EL element is transmitted through an electrode having a light-transmitting property is reduced as much as possible, so that attenuation of light is suppressed. Thus, a light-emitting device capable of modulation of light emission colors which has a high luminance and a long lifetime can be provided. In the light-emitting device, voltages applied to the organic EL elements, which deteriorate individually, are separately controlled, whereby the color tone can be kept constant for a long period.
