An object is to provide a light-emitting element capable of further suppressing the spread of a light-emitting region and further improving directivity. A light-emitting element is provided which includes at least a phosphor layer and an emission angle selection layer which emits light incident at a predetermined angle, in which the phosphor layer includes a phosphor and a light scatterer, and the phosphor layer and the light emission angle selection layer are arranged in this order.

Light-emitting element, light source device and projector

A light source unit includes a substrate that is rotatable, a phosphor layer disposed at a center of the substrate, a light source that irradiates the phosphor layer with exciting light, and a support section that supports a portion, of the substrate, except for the center of the substrate. This makes it difficult for heat generated in the phosphor layer to travel to a motor through the substrate.

Light source unit and projection-type display

A light source unit includes a light source section and a fluorescent structure. The fluorescent structure includes a fluorescent part where light from the light source section enters. The fluorescent part includes a transparent grain in addition to a plurality of phosphors.

Light source unit and projection display apparatus

A light-emitting device of an embodiment of the present disclosure includes a first base, a second base that is disposed to face the first base, and a phosphor layer that is provided to be filled with a plurality of phosphor particles between the first base and the second base.

Light-emitting device, light source unit, and projection display apparatus

A light source unit according to an embodiment of the disclosure includes a substrate configured to be rotatable, a phosphor layer disposed at a center of the substrate, a light source that irradiates the phosphor layer with exciting light, and a support section that supports a portion, of the substrate, except for the center of the substrate. This makes it difficult for heat generated in the phosphor layer to travel to a motor through the substrate.
