    • PROBLEM TO BE SOLVED: To display a bright image high in contrast in an image display device using phosphor particles. SOLUTION: The image display device 100 is constituted of a plurality of pixels 102 arranged at an inner face side of a front plate 101 with translucency. Each pixel includes a light emission layer 104 in which phosphor particles 105 are dispersed in a background medium 106 having the same refractive index as that of the phosphor particle, an excitation source 103 exciting the phosphor particles to make them emit light, and a refractive index distribution structure 107 arranged between the front plate and the light emission layer and having a periodic refractive index distribution in a direction along an inner surface of the front plate.

    • PROBLEM TO BE SOLVED: To provide a wavelength converting structure able to effectively convert UVC to visible lights, therefore, provide a visible light source with a large surface area, and a method for manufacturing and using the same. SOLUTION: The wavelength converting structure comprises a base material and a wavelength converting coat layer deposited on the base material and containing (a) a phosphor powder excited by UVC and (b) an anti-UVC binder. In the structure, the thickness of the wavelength converting coat layer is 2-10 times the average particle size of the phosphor powder and the amount of the phosphor powder in the wavelength converting coat layer conforms to at least one of the following requirements: (i) the volume ratio of the phosphor powder in the wavelength converting coat layer (based on the sum total volume of the phosphor powder and the binder) should be 30-85%, (ii) the weight ratio of the phosphor powder to the adhesive should range from 1:1 to 20:1.
