Abstract
A light field liquid crystal display cell with a colored seal and pattern layer applied to the cell substrates. Dark segments are displayed against a lighter background. The light field background is created without masking the cell substrates, polymeric substances can be used to space and seal the cell substrates, and the cell is amenable for the construction of large displays.
