Led unit for display and display apparatus having the same

A light emitting device for a display, comprising:

• a transparent member through which light can be transmitted, laterally extending in a first direction, and having a first region and a second region surrounding the first region;
• a first light emission region disposed on the transparent member;
• a second light emission region disposed on the first light emission region;
• a third light emission region disposed on the second light emission region;
• a support substrate disposed on the first, second, and third light emission regions, the first, second, and third light emission regions being disposed between the support substrate and the transparent member;
• a first electrode pad, a second electrode pad, a third electrode pad, and a fourth electrode pad disposed between the transparent member and the support substrate;
• a plurality of vias electrically connecting the first, second, third electrode pads to the first, second, and third light emission regions, respectively;
• and
• a plurality of insulative layers having different refractive indices interposed between the first and second light emission regions,
• wherein the fourth electrode pad is electrically connected to at least one of the vias,
• wherein each of the first, second, and third light emission regions is disposed in the first region of the transparent member and does not overlap the second region of the transparent member in a second direction crossing the first direction,
• wherein each of the first, second, and third light emission regions includes a first conductivity type semiconductor layer, a second conductivity type semiconductor layer, and an active layer therebetween, and
• wherein one of the first, second, and third light emission regions has a different stacked sequence of the first conductivity type semiconductor layer, the second conductivity type semiconductor layer, and the active layer than the remaining ones of the first, second, and third light emission regions.
