1. A display system comprising;
- a plurality of semiconductor light-emitting devices embedded in an insulation of said semiconductor light-emitting devices having a lower end surface disposed on a substrate, an exposed upper end portion and a light-emitting region proveded between said lower end surface and siad upper ind portion, wherein a planar surface of the insulation layer is coplanar with the exposed upper end portion; and
a conductor film proveded on an upper surface of said insulation layer and in contact with an upper end portion electrode on said exposed upper end portions of said semicondutor light-emitting devices;
where said light-emitting region is at a slant angle relative to said lower end surface.

Abstract
Disclosed are a display system and a method of producing the same. In the present invention, a hexagonal pyramid shaped GaN semiconductor light-emitting device selectively crystal-grown is fixed on an upper surface of a substrate by embedding it in an insulation layer formed of an epoxy resin. Then the insulation layer is selectively dry etched in an oxygen plasma atmosphere to expose an upper end portion of the GaN semiconductor light-emitting device. A conductor film is formed on the entire surface, and a required portion of the conductor film is left as a lead-out electrode while the unrequired portion is removed by lithography.

15. A display system comprising:
-
at least one semiconductor light-emitting devices embedded in an insulation layer, each of said at least one semiconductor light-emitting devices having a lower end surface located in said insulation layer and disposed on a substrate, an exposed upper end portion, wherein a planar surface of the insulation layer is coplanar with the exposed upper end portion;
a light-emitting region provided between said lower end surface and said upper end portion; and
a conductor film provided on an upper surface of said insulation layer, said conductor film further being in contact with an upper end portion electrode on said exposed upper end portions of said semiconductor light-emitting devices;
wherein said light-emitting region is at a slant angle relative to said lower end surface.
