A color conversion substrate includes a transparent substrate having a main surface, a plurality of phosphor patterns arranged on the main surface and each of the phosphor patterns having side faces, and a reflective film that reflects light and is formed on at least the side faces of the phosphor patterns. An air layer is defined between the main surface and the phosphor patterns.
