光がカットされ黄色光になることがわかる。As is clear from Figure 2, due to the effect of the blue absorption film,
It can be seen that the transmittance of light with a wavelength of 00 nm or less becomes small, and as a result, light with a short wavelength of 500 nm or less, that is, blue light, is cut and becomes yellow light.
