<p>It is desired to provide a phosphor particle that has a smaller content of a phosphor, and therefore is inexpensive. A phosphor particle having a phosphor layer made of a phosphor on its surface and containing an inorganic non-phosphor material inside is provided. Further, the foregoing phosphor particle is further arranged so that the phosphor layer contains a compound made of M<1>, Al, and O (the M<1> is at least one metal element selected from Ba, Sr, Mg, and Ca) as a matrix and Eu and/or Mn as an activator. Furthermore, the foregoing phosphor particle is further arranged so that the phosphor layer contains a compound made of Zn, Si, and O as a matrix and Tb and/or Mn as an activator. Furthermore, the foregoing phosphor particle is further arranged so that the phosphor layer contains a compound made of M<4> and O (the M<4> is at least one metal element selected from Y, Gd, and B) as a matrix and Eu as an activator.</p> |
