Abstract
A polymer dispersion type liquid crystal display element having liquid crystal droplets dispersed and held in a continuous matrix phase including polymer compound or a three dimensional network form of matrix including polymer compound dispersed between a pair of substrates, each having an inside electrode. The liquid crystal droplets are in all areas but for an area in the vicinity of the interfaces between the substrates. The liquid crystal droplets are ellipsoid of revolution forms of substantially the same size.
Claims5
