Computer-generated hologram and its fabrication process, reflector using a computer-generated hologram, and reflective liquid crystal display |
摘要 |
The invention provides a computer-generated hologram which can be viewed in white at the desired viewing region and a reflective liquid crystal display using the same as a reflector. The computer-generated hologram H is designed to diffuse light having a given reference wavelength » STD and incident thereon at a given angle of incidence ¸ in a specific angle range. In a range of wavelengths » MIN to » MAX including the reference wavelength » STD wherein zero-order transmission light or zero-order reflection light of incident light on the computer-generated hologram at a given angle of incidence is seen in white by additive color mixing, the maximum diffraction angle ² ZMIN of incident light of the minimum wavelength » MIN in the wavelength range and incident at the angle of incidence ¸ is larger than the minimum diffraction angle ² 1MAX of incident light of the maximum wavelength » MAX in the wavelength range and incident at said angle of incidence ¸. |
