Claim of US Patent No. 10,559,617
1. A device comprising:a light emitting semiconductor structure;
a wavelength converting structure disposed on a top surface of the light emitting semiconductor structure;
a light blocking structure disposed along a sidewall of the light emitting semiconductor structure and the wavelength converting structure, the light blocking structure being a same color as an off-state color of the wavelength converting structure; and
a reflective layer disposed between the light blocking structure and the semiconductor structure, the reflective layer including alternating first and second insulating layers, the first insulating layers having a different index of refraction from the second insulating layers.
