Patent ID: 8664677

Claim:
A light-emitting element, comprising: (A) a first electrode; (B) an organic layer including a light-emitting layer made of an organic light-emitting material; (C) a semi-transmissive/reflective film; (D) a resistance layer; and (E) a second electrode, wherein, the first electrode is configured to reflect light coming from the light-emitting layer, the second electrode is configured to allow light coming from the semi-transmissive/reflective film after passing therethrough, the semi-transmissive/reflective film on the organic layer has an average film thickness of 1 nm to 6 nm both inclusive, the light from the light-emitting layer is made to resonate between (i) a first interface between the first electrode and the organic layer, and (ii) a second interface between the semi-transmissive/reflective film and the organic layer, and a part of the light is emitted from the semi-transmissive/reflective film.
