摘要：
A red phosphor of high efficiency and a method for producing it are provided. A white light source and an illumination device that allow illumination with the pure white color using the red phosphor are also provided. In addition, a liquid crystal display device using the red phosphor and exhibiting good color reproducing performance is provided. The red phosphor contains an element A, europium (Eu), silicon (Si), carbon (C), oxygen (O) and nitrogen (N) in the ratios of the numbers of atoms of the following compositional formula (1): [Chemical Formula 1] [A(m-x)Eux][Si(9-y)Cy]OnN[12-2(n-m)/3] compositional formula (1) where the element A is at least one of magnesium (Mg), calcium (Ca), strontium (Sr) and barium (Ba), and where m, x and n in the compositional formula (1) satisfy the relationships of 3
