Image display device and light emission device

Abstract

An image display device including a light emission section which emits light to an intensity adjusting section and a wavelength conversion section which change the intensity and wavelength of the emitted light. Phosphors and phosphor like materials are employed in wavelength conversion and a liquid crystal is employed for the light adjustment. The light emission device may include plural semiconductor light emitting elements having a different wavelength ranges such as diodes stacked in a compact and predetermined order such that wavelengths of light from each diode are emitted from the light emitting elements.

1 . An image display device comprising: 
 a light source section including semiconductor light emitting elements as light sources;    a light adjustment section arranged opposite said light source section and which adjusts intensity of light incident thereto; and    a wavelength conversion section opposite said light source section and having a plurality of pixels, which adjusts intensity of light incident thereto for each of said pixels to a different frequency range;    wherein lights emitted from said light source section pass through said light adjustment section and said wavelength conversion section to be output as transmitted lights adjusted in intensity and converted in frequency.
