摘要:
An organic EL display device (1) including organic EL light-emitting regions which includes a red-light emitting layer (111), a green-light emitting layer (112), and a blue-light emitting layer (113) that are arranged on a main substrate (101) includes: a first light-adjusting layer (109) including a first portion (B) and a second portion (M), the first portion selectively transmitting desired blue light, and the second portion absorbing visible light other than at least the desired blue light; and a second light-adjusting layer (106) selectively absorbing light with a wavelength between desired red light and desired green light at an entire surface, in which the blue light-emitting layer (113) is overlaid with the first portion (B), and a bank which is a non-light emitting portion is overlaid with the second portion (M). The first portion and the second portion may be integrally formed of a same material, and the second portion may absorb an entire range of visible light.
