RED FLUORESCENT MATERIAL, METHOD FOR PRODUCING RED FLUORESCENT MATERIAL, WHITE LIGHT SOURCE, ILLUMINATING DEVICE, AND LIQUID CRYSTAL DISPLAY

[Problems to Be Solved] The present invention provides an efficient red fluorescent material and a method for producing the same, provides a white light source and an illuminating device each of which uses this red fluorescent material to achieve snow-white lighting, and furthermore provides a liquid crystal display having excellent color reproduction. [Means to Solve the Problem] The red fluorescent material contains an element A, europium (Eu), silicon (Si), carbon (C), oxygen (O), and nitrogen (N), at an atomic ratio of the following composition formula (1). [Chemical Formula 1] [A(m-x)Eux][Si(9-y)Cy]OnN[12-2(n-m)/3]Composition Formula (1) Note that, in the composition formula (1), the element A is a group 2 element including at least calcium (Ca) and strontium (Sr). Also, note that, in the composition formula (1), m, x, y, and n satisfy 3
