Title:
FLUORESCENT SUBSTRATE, LIGHT SOURCE DEVICE, AND PROJECTION-TYPE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/181768
Kind Code:
A1
Abstract:
According to one embodiment of the present invention, a fluorescent substrate is provided with: a substrate that is rotatably configured; and a fluorescent layer that is disposed at the center of the substrate. Consequently, in the cases where warping is generated in the substrate due to stress caused by heat expansion of the fluorescent layer and the substrate, the displacement amount of the fluorescent layer is small compared with the cases where an annular fluorescent layer is disposed on the outer periphery of the substrate.
