Abstract

A large area liquid crystal display comprises a layer of liquid crystal material between two cell walls. One cell wall has a common sheet electrode. The other cell walls comprise a plurality of addressing tiles electrically connected together. Driver circuits at the display edges apply addressing voltages. Each addressing tiles comprises a series of m data electrodes and n gate electrodes arranged to form an m.times.n matrix array of electrode intersections. At each intersection is a pixel patch electrode and a non linear element connected to adjacent source and gate electrodes and to the pixel electrode. The data and gate electrodes continue across the tile surface and around its edges. Adjacent tiles are electrically connected together by an anisotropic glue, or by solder bumps, or electrical bridges. The liquid crystal material may be encapsulated in a polymer matrix or be a non-encapsulated layer. Dyes may be incorporated in the liquid crystal material. The pixel electrode may be formed as a group of three independently addressed electrodes each providing a different color so the display may be a multi-color display.
