LAMINATED MULTICOLOR LIGHT EMITTING DISPLAY APPARATUS

摘要

<P>PROBLEM TO BE SOLVED: To provide a laminated multicolor light emitting display apparatus which reduces the external-light reflectance of a green wavelength region having a high visual sensitivity and reduces the substantial effect of the external-light reflection. Ž<P>SOLUTION: The laminated multicolor light emitting display apparatus 1 includes: a substrate 10; a lower reflecting electrode 20 disposed on the substrate 10; a first EL layer 30 which is disposed on the lower reflecting electrode 20 including a first light emitting layer radiating green; a first intermediate-electrode layer 40 which is disposed on the first EL layer and is a translucent reflecting electrode; a second EL layer 50 which is disposed on the first intermediate-electrode layer 40 including a second light emitting layer radiating a predetermined color; and an upper electrode 80 disposed above the second EL layers 50. In the laminated multicolor light emitting display apparatus 1, the lower electrode 20 and the first intermediate-electrode layer 40 function as an optical resonator and the external-light reflection is made minimum in each green wavelength region.
