based on orientation effects in which the liquid crystal remains transparent

Full Title

Devices or arrangements for the control of the intensity, colour, phase, polarisation or direction of light arriving from an independent light source, e.g. switching, gating or modulating; Non-linear optics > for the control of the intensity, phase, polarisation or colour (G02F1/29, G02F1/35 take precedence) > based on liquid crystals, e.g. single liquid crystal display cells > characterised by the electro-optical or magneto-optical effect, e.g. field-induced phase transition, orientation effect, guest-host interaction or dynamic scattering > based on orientation effects in which the liquid crystal remains transparent
