Abstract
An organic electroluminescent (EL) element array includes a substrate, a first organic EL element emitting red light, a second organic EL element emitting green light, and a third organic EL element emitting blue light. The first, second, and third organic EL elements each include a first electrode, an organic compound layer, and a light-transmissive second electrode arranged on the substrate in that order. The second electrode of the first organic EL element has a semitransparent reflective layer. The first electrode of the first organic EL element has a reflective face and a resonant structure located between the reflective face and the semitransparent reflective layer. The second and third organic EL elements each has a resonant structure located between a reflective face of the first electrode of the second or third organic EL element and a light-extracting face of the transparent layer of the second or third organic EL element.
