Abstract
A liquid crystal display cell having a compensation layer of (polymer) material deposited from the gaseous phase. To obtain a smaller angle dependence, the birefringence of the compensation layer is rendered complementary to that associated with a given voltage across the liquid crystal cell by giving the optical axis of the compensation layer an angle to the direction transverse to the cell.
Claims8
A retardation layer comprising a layer of optically anisotropic material, the optically anisotropic layer being provided by means of gaseous phase deposition.
