Claim:
1. A display device including light emitting devices, comprising: a first light emitting device containing a first semiconductor active region located over a substrate, wherein the first semiconductor active region has a first band gap that emits light at a first wavelength; and a second light emitting device containing a second semiconductor active region located over the substrate and a conversion medium overlying the second semiconductor active region, wherein the conversion medium converts shorter wavelength light emitted from the second semiconductor active region to light having a target color; wherein: the first semiconductor active region is located in a first nanowire; the second semiconductor active region is located in a second nanowire; the second semiconductor active region has the first band gap; the conversion medium comprises an inorganic phosphor, organic luminescent material or quantum dots; and the conversion medium generates the target color having a longer wavelength than the shorter wavelength light emitted from the second semiconductor active region, and direct emission from the first light emitting device generates an additional color to achieve different color subpixels in a display.
