ORGANIC ELECTROLUMINESCENT COLOR LIGHT-EMITTING DEVICE

摘要

An organic EL light-emitting device comprising 'on a supporting substrate (100)' a first pixel (10) provided with a first organic EL element emitting light having an emission peak wavelength of ?₁ and a second pixel (20) provided with a second organic EL element emitting light having an emission peak wavelength of ?₂, wherein the emission peak wavelength of ?₂ is longer than ?₁, each of the first and second organic EL elements comprises at least a light reflecting electrode (11, 21), an organic light-emitting medium layer, and a translucent electrode formed sequentially in this order in the light taking-out direction, and m₁ and m₂ defined by the formula (1) below satisfy the following relation: m₂+1.3>m₁> m₂+0.7 (m₁ and/or m₂ is substantially an integer of 0 or above). m
