LIGHT SOURCE DEVICE AND PROJECTION-TYPE DISPLAY DEVICE

摘要

A light source device according to one embodiment of the present disclosure comprises: a substrate configured to be rotatable; a phosphor layer disposed in the center of the substrate; a light source that irradiates excitation light on the phosphor layer; and a support part that supports a portion of the substrate other than the center of the substrate. Due to this configuration, heat which is generated in the phosphor layer is not readily transmitted to a motor through the substrate.
