Abstract
An image display device which reduces speckles in an image display device using a laser source includes: a laser source which emits excitation light; a collecting lens which collects the excitation light; a deflecting element which scans the excitation light collected by the collecting lens; and a light conversion panel which converts a wavelength of the excitation light scanned by the deflecting element and emits fluorescence, wherein the light conversion panel includes a plurality of phosphor layers which are planarly disposed, absorb the excitation light, and emit the fluorescence.
