1. A display apparatus comprising:
a first light-emitting device comprising a first pixel electrode, a first light-emitting layer over the first pixel electrode, and a common electrode over the first light-emitting layer;
a second light-emitting device comprising a second pixel electrode, a second light-emitting layer over the second pixel electrode, and the common electrode over the second light-emitting layer;
a first insulating layer over the first pixel electrode and the second pixel electrode;
a second insulating layer over the first insulating layer;
a first color conversion layer overlapping with the first light-emitting device; and
a second color conversion layer overlapping with the second light-emitting device,
wherein the first insulating layer covers an end portion of the first pixel electrode and an end portion of the second pixel electrode,
wherein the second insulating layer is in direct contact with side surfaces of the first light-emitting layer and the second light-emitting layer,
wherein the first light-emitting device and the second light-emitting device are each configured to emit blue light,
wherein the first color conversion layer is configured to convert light emitted from the first light-emitting device into light having a different wavelength, and
wherein the second color conversion layer is configured to convert light emitted from the second light-emitting device into light having a different wavelength.
