A display device comprising:
- an insulating reflective layer on a substrate;
- and
- a light emitting element on the insulating reflective layer,
- wherein the insulating reflective layer comprises a first layer and a second layer on the first layer,
- the first layer includes a first area of a shared layer that is at least a portion of the insulating reflective layer,
- the second layer includes a second area of the shared layer,
- the first layer comprises a first distributed Bragg reflector configured to reflect light in a first wavelength band, and
- the second layer comprises a second distributed Bragg reflector configured to reflect light in a second wavelength band,
- wherein a first central wavelength of the first wavelength band is different from a second central wavelength of the second wavelength band,
- wherein the second central wavelength is smaller than the first central wavelength, and
- wherein the first layer is closer to the substrate than the second layer.
A display device comprising:
- an insulating reflective layer on a substrate;
- and
- a light emitting element on the insulating reflective layer,
- wherein the insulating reflective layer comprises a first layer and a second layer on the first layer,
- the first layer includes a first area of a shared layer that is at least a portion of the insulating reflective layer,
- the second layer includes a second area of the shared layer,
- the first layer comprises a first distributed Bragg reflector configured to reflect light in a first wavelength band, and
- the second layer comprises a second distributed Bragg reflector configured to reflect light in a second wavelength band, wherein:
- the shared layer comprises a first shared layer in the first area and a second shared layer in the second area,
- the first layer comprises a (1_1)-th layer, a (1_2)-th layer on the (1_1)-th layer, and the first shared layer on the (1_2)-th layer, and
- the second layer comprises a (2_1)-th layer, and the second shared layer on the (2_1)-th layer.
A display device comprising:
- electrodes on a substrate;
- an insulating reflective layer on the electrodes;
