Title:
IMAGE DISPLAY DEVICE AND LIGHT SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/208572
Kind Code:
A1
Abstract:
An image display device according to an embodiment of the present technology includes one or more solid-state light sources, a light-emitting body (121), a crystalline member (122), a light emission unit, and an optical filter. The light-emitting body (121) is excited by the output light from the one or more solid-state light sources to thereby emit light. The crystalline material (122) is rotatable, and supports the light-emitting body (121) with the crystal axis direction (130) established in a direction different from the optical axis direction of the output light. The light emission unit emits synthesized light including at least a portion of the output light and the light from the light-emitting body (121). The optical filter includes a dielectric multilayer whereon the synthesized light from the light emission unit is incident.
