Abstract:
A liquid crystal display device (10) includes a liquid crystal material (15) such as PSCT disposed between first (12) and second glass substrates (14), and means for applying an electric field to the liquid crystal material so as to effect switching of the liquid crystal material. The liquid crystal material (15) is of the type which exhibits at least three stable states in dependence upon an electric field applied, and which maintains its state (exhibits memory) when the electric field is removed. This display device (10) also includes a colour filter (24) comprising at least two different colours. Liquid crystal display device (10) provides an extremely energy efficient, colour liquid crystal display device having grey scale capability. The energy demand of the device is so low, it is envisaged it will be incorporated into consumer items such as palmtop computers, advertising materials, packaging, handheld computer games, etc.
