摘要： This invention relates to coated particles used as phosphor particles for a phosphor screen of a display and a coating method for such particles. In the coating method of the present invention, first particles having a mean particle diameter of 3 to 10 μm are fluidized, and slurry drops obtained by suspending second particles having a mean particle diameter of 5 to 500 nm are generated from a spray nozzle or the like. Then, the fluidized first particles and the slurry drops are collided with each other, and thereby the second particles are coated on the surfaces of the first particles. Thereby, this invention is able to present coated particles wherein each surface of the first particles is uniformly coated with the second particles that are more microscopic than the first particles.

摘要： A liquid crystal display capable of expanding a color reproduction range in the case where a cold cathode fluorescent lamp is used as a light source is provided. A green phosphor of the cold cathode fluorescent lamp includes BaMgAl10O17:Eu, Mn. The wavelength range of a green emission spectrum is located on a shorter wavelength side than that in the case where the green phosphor includes LaPO4:Ce, Tb, so the spectral width of the green emission spectrum is narrower. Therefore, an overlap between the wavelength ranges of green display light and red display light is reduced. Moreover, the spectral characteristics of blue display light (blue spectral characteristics) are set so as to satisfy predetermined conditional expressions. An overlap between the wavelength ranges of the green display light and the blue display light is also reduced.
