发明名称 Display device
摘要 The purpose of the present invention is to provide a display device in which light emitted from a phosphor is used with enhanced efficiency. A display device is provided with a light source unit for emitting light, a plurality of phosphors for emitting light upon incidence thereon of light from the light source unit, a transparent substrate disposed on the phosphors, a color conversion substrate formed between the phosphors and the transparent substrate and including a reflective member and a low refractive index layer having a refractive index lower than that of the phosphors, and an air layer between the phosphors and the light source unit.

主权项 1. A display device, comprising: a light source unit that emits light; and a color conversion substrate above the light source unit, including: a transparent substrate;a plurality of phosphors arranged on a main surface of the transparent substrate facing the light source unit, said phosphors receiving light from said light source unit and emitting light in response thereto;a low refractive index layer that is formed between the phosphors and the transparent substrate and that has a lower refractive index than the phosphors; anda reflective member that reflects light that is emitted sideways by the respective phosphors, said reflective member having a plurality of openings therein and being disposed so as to cover at least edges of the respective phosphors, wherein the phosphors and the light source unit are configured to define an air layer therebetween.
