Light emitting device, method of manufacturing light emitting device, and image display apparatus

A method of manufacturing a light emitting device, the method comprising:

• forming a mesa section through etching a compound semiconductor layer from a side of a first electrical conductivity type layer, the compound semiconductor layer including the first electrical conductivity type layer, an active layer, and a second electrical conductivity type layer that are stacked in this order, the mesa section including the first electrical conductivity type layer, the active layer, and a portion of the second electrical conductivity type layer;
• embedding an insulating film in a first groove section formed around the mesa section through the etching;
• forming a second groove section having a tapered shape through etching the insulating film;
• and
• forming a first transparent electrode layer on the first electrical conductivity type layer in the mesa section after forming a first light reflection film on a side surface and a bottom surface of the second groove section, the first transparent electrode layer including an enlarged-width section that is larger in width than the mesa section.

An image display apparatus, comprising

• a light emitting device,
• the light emitting device including:
• a driving substrate;
• a compound semiconductor layer that has a first surface serving as a light exit surface and a second surface located on a side opposite to the first surface and opposed to the driving substrate, the compound semiconductor layer including a first electrical conductivity type layer, an active layer, and a second electrical conductivity type layer that are stacked in this order from a side of the driving substrate, and including a mesa section that includes the first electrical conductivity type layer, the active layer, and a portion of the second electrical conductivity type layer;
• a first transparent electrode layer formed on a side, of the first electrical conductivity type layer, that is closer to the driving substrate, and including an enlarged-width section that is larger in width than the mesa section;
• and
• a first light reflection film provided around the mesa section with a first insulating film interposed therebetween, the first light reflection film forming an inclined surface that is at an acute angle with respect to the first surface.
