ABSTRACT:
A display device has a light source that radiates light from a light-emitting portion. A light guide body receives an incident light from the light-emitting portion of the light source and emits light. A display element is illuminated by light emitted from the light guide body and has a color filter having a coloring layer of RGB. A filter layer reflects components of light having a wavelength in a preselected region of 570 nm to 590 nm among the light radiated from the light source and emitted from the light guide body. A phosphor is excited by the components of light in the preselected region reflected by the filter layer and emits red light that passes through the filter layer and through the color filter of the display element.
