A liquid crystal display panel photographed between crossed polarisers — the molecular orientation domains appearing as complex coloured birefringent patterns in violet, cyan, gold, and magenta against a black background.
Description
Liquid crystal materials exhibit birefringence — a property of some optically anisotropic materials that splits incident light into two polarised components with different refractive indices. When a thin section of liquid crystal material is placed between two crossed linear polarisers, the different domains of molecular orientation produce different interference colours, creating the vivid abstract patterns of polarised light microscopy. This image was made using a section of liquid crystal material on a light box with a linear polariser below, photographed through a second polariser at 90 degrees to the first. Rotating the upper polariser by small increments changes the colour of each domain. The image shown captures the position of maximum colour differentiation, the domains appearing in vivid complementary colours that create a map of the material’s molecular orientation.
