Claim 0:
1. A display device comprising:
a substrate including a first emitter and a second emitter thereon,
the first emitter including a first lower active quantum well (QW) region that has a first emission spectrum spanning a first spectral range, and
the second emitter including (i) an upper active QW region that has a second emission spectrum spanning a second spectral range that is distinct from the first spectral range, (ii) a second lower active QW region having the first emission spectrum and being located between the upper active QW region and the substrate, and (iii) a barrier layer between the second lower active QW region and the upper active QW region for suppressing emission of the second lower active QW region, an area of the first emitter decreasing as a height of the first emitter, relative to a top surface of the substrate, increases.
