发明名称 Method of manufacturing image display device and method of selecting color filter
摘要 A method of manufacturing an image display device which is configured to produce high luminance while maintaining color reproductivity and a method of efficiently selecting a combination of a light emitting device and a color filter. A method of manufacturing an image display device includes preparing a light emitting device which has a light source, a green fluorescent material and a red fluorescent material activated with tetravalent manganese ions, and configured to emit light which includes a visible light region, providing a color filter candidate which include red, green, and blue pixels in which the ratio of an integral value of the wavelength range of 560 to 640 nm with respect to the ratio of an integral value of the wavelength range of 460 to 640 nm in a spectral transmittance curve of the green pixel is 23% or greater, providing a color filter configured to satisfy a NTSC ratio of 65% or greater when the color filter candidate and the light emitting device are combined, and constructing an image display device with the use of the color filter, the light emitting device, and a controlling member for optical transmission.

主权项 1. A method of manufacturing an image display device comprising: providing a light emitting device which comprises a light source, a green fluorescent material and a red fluorescent material activated with tetravalent manganese ions and configured to emit light which comprises visible region light; providing a color filter candidate which comprises red, green, and blue pixels in which a ratio of an integral value of the wavelength range of 550 to 640 nm based on an integral value of the wavelength range of 460 to 640 nm in a spectral transmittance curve of the green pixel is 33% or greater, providing a color filter configured to satisfy a NTSC ratio of 65% or greater when the color filter candidate and the light emitting device are combined; and constructing an image display device of the color filter, the light emitting device, and a controlling member for optical transmission.
