Wavelength-selecting optical element capable of preventing color shift dependent on the viewing direction and optical display provided with the same |
摘要 |
A wavelength-selecting optical element includes a cholesteric layer that reflects or transmits either of a right-handed circularly polarized light component and a left-handed circularly polarized light component in a selected wavelength band of an incident light; and a diffusing layer disposed on the exit side of the cholesteric layer to diffuse the circularly polarized light component reflected or transmitted by the cholesteric layer. The cholesteric layer may be a color filter having a red, a green and a blue pixel region for each of pixels. Each of the pixel regions reflects or transmits either of a right-handed circularly polarized light component and a left-handed circularly polarized light component in a selected wavelength band of an incident light.
