Abstract: A top emission organic EL light-emitting device on a substrate is provided which emits light from the side opposite the substrate. The organic EL light-emitting device includes a light reflection layer, a first electrode made of a transparent conductive material, a function layer including an organic EL luminescent layer that emits light, and a second electrode disposed in that order on the substrate. The second electrode includes a semi-transparent semi-reflective layer that transmits part of the light emitted from the organic EL luminescent layer and reflects the rest of the light. The organic EL light-emitting device also includes a dielectric mirror disposed between the function layer and the light reflection layer. The dielectric mirror acts as an optical resonator that strengthens light having a specific wavelength.

Abstract: The invention provides a light-emitting apparatus that has a plurality of pixels each of which has a set of four sub pixels including a red, a green, a blue, and a remaining sub pixel, together making up a display screen. Each of the sub pixels has a light-emitting layer and color filter that transmits light corresponding to the sub pixel. The light-emitting layer includes a white light-emitting material that emits three-peak white light, with an emission spectrum having a red peak, a green peak, and a blue peak falling within the wavelength range of red light, of green light, and of blue light, respectively. Low intensity regions exist between the red peak and the green peak and between the green peak and the blue peak. The light-emitting layers of the sub pixels extend along the display screen. The color filters overlap the light-emitting layers in a plan view.
