Circularly polarized light separating layer, optical element, illumination device, and liquid crystal display device |
| abstract |
A liquid crystal display device and the like having excellent brightness and visibility can be formed by obtaining a circularly polarized light separating layer having excellent viewing angle characteristics, which suppresses coloring in a visual direction in a perspective direction, while enabling luminance of a liquid crystal display device or the like to be improved. Obtaining optical elements and lighting devices. Two or more cholesteric liquid crystal polymer layers overlap to change the helical pitch of the Grandian orientation in the thickness direction, and the circular dichroism extends to a wavelength range of 50 nm or more including a wavelength of 520 nm. When the reflected light or transmitted light is linearly polarized through a quarter-wave plate, the degree of polarization is such that the wavelength of linearly polarized light in the visible light region showing the maximum value of the degree of polarization is 520 nm or less, or the circle. For forming an illuminating device or a liquid crystal display device in which the integration of the degree of polarization of linearly polarized light in the visible light region of the wavelength region exhibiting polarization dichroism has a higher degree of polarization on the short wavelength side than on the long wavelength side based on the wavelength light of 520 nm. Circularly polarized light separating layer for formation. [Selection diagram] Fig. 1 |
