Abstract:
1. A multicolor light-emitting organic electroluminescent (EL) display device including a plurality of organic EL light-emitting regions each of which emits red light, green light, or blue light and a non light-emitting region that are arranged on a main substrate, the multicolor light-emitting organic EL display device comprising: a first light-adjusting layer; and a second light-adjusting layer, wherein the first light-adjusting layer is a magenta color filter and is laid over a light-emitting region of the blue light, a light-emitting region of the red light, and the non light-emitting region, the second light-adjusting layer is made of resin, selectively absorbs light having a wavelength intermediate between the red light and the green light, and has: a maximum value of a transmission factor of visible light being 80% or greater; and a minimum value of the transmission factor being 25% or smaller; a wavelength indicating 60% of transmission factor in ranges between 550 nm and 580 nm and between 590 nm and 620 nm; and a wavelength indicating a minimum value of the transmission factor in a range between 580 nm and 600 nm, and the second light-adjusting layer is laid over the light-emitting region of the blue light, a light-emitting region of the green light, the light-emitting region of the red light, and the non light-emitting region.
