Abstract:
The present invention includes: a reflective electrode (2); a translucent electrode (10); an organic EL layer (21) for emitting blue light, the organic EL layer being sandwiched between the reflective electrode and the translucent electrode; a red fluorescent substance layer (13) for converting the light from the organic EL layer (21) into red light; a green fluorescent substance layer (14) for converting the light from the organic EL layer (21) into green light; and a blue pixel including a light-distribution-characteristic adjusting layer (15) for adjusting a light distribution characteristic of the light from the organic EL layer (21), the present invention being structured such that the reflective electrode (2) and the translucent electrode (10) produce a microcavity effect.
