Abstract
Provided is a multicolor display apparatus including a plurality of organic light-emitting devices each including a pair of electrodes of an anode and a cathode; and an organic compound layer interposed between the pair of electrodes and including a light-emitting layer. The viewing angle characteristics of the organic light-emitting device showing an emission color with a highest visual sensitivity is such that a peak wavelength of emission spectrum and a peak wavelength of multiple interference spectrum due to the organic light-emitting device are offset with respect to each other so that the color shift of a display image on the multicolor display apparatus depending on a viewing angle is suppressed.
