Display device panel with an emitting fluorescent film composed of red fluorescent particles covered with a red pigment

摘要

A display device which includes, a display panel, a red emitting fluorescent film, a green emitting fluorescent film, and a blue emitting fluorescent film, each of the fluorescent films being formed on an inner surface of the display panel. The red emitting fluorescent film contains red fluorescent particles having an average particle diameter ranging from 6 to 12 μm and covered with red pigment having an average particle diameter ranging from 1/100 to 1/10 of the average particle diameter of the red fluorescent particles, the red emitting fluorescent particles are formed of Y₂O₂S:Eu, a concentration of Eu in the red emitting fluorescent film is 60 ppm or less, and the x-value of luminescent chromaticity of the red emitting fluorescent film is not less than 0.620.
