摘要： To realize a configuration in which only light having an unnecessary wavelength is cut so that light having a necessary wavelength may be obtained efficiently, a filter layer that selectively reflects light having a particular wavelength and a phosphor layer containing a phosphor that is excited with the light having the particular wavelength to emit light are provided. Thus, the light reflected by the filter layer is converted into light having a different wavelength by the phosphor layer so as to pass through the filter layer. The filter layer is placed between a display element and a light source of an illuminating device, and the filter layer that selectively reflects a light component to be absorbed by the display element is used, whereby the light component to be absorbed by the display element is converted by the phosphor layer so as to pass through the display element. Accordingly, the illuminating device and a display device having very high luminance efficiency and color reproducibility may be realized.

摘要： 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.
