摘要： A display device (5000) comprising one or more light emitters (5010) configured to emit light having more than one polarization state; a waveguide (5015) disposed with respect to said one or more light emitters (5010) to receive light from said one or more light emitters such that at least some of said light is guided therein by total internal reflection, said waveguide (5015) configured to eject light having a first polarization state out of said waveguide (5015); a spatial light modulator (5025) disposed with respect to said waveguide (5015) to receive said light ejected from said waveguide (5015) and modulate said light; and a light recycling system (5030a, 5030b) configured to convert light having a second polarization state to light having the first polarization state.

摘要： Provided is a fluorescent material with high brightness. The fluorescent material includes a nitride fluorescent material comprising La, Ce, Si, and N; and a first phosphorus compound disposed on a surface of the nitride fluorescent material. The first phosphorus compound includes at least one selected from the group consisting of lanthanum phosphate, lanthanum hydrogen phosphate, and hydrates thereof. A content of phosphorus atoms in the fluorescent material is 0.07% by mass or higher and 0.8% by mass or lower.
