The invention provides a liquid crystal display having high reliability, which is excellent in terms of optical characteristics, heat resistance, and shock resistance, wherein a liquid crystal display consisting of a cholesteric liquid crystal, a chiral nematic liquid crystal or a liquid crystal 1 layer, being a combination thereof, which is roughly pillar-like and polygonal in section or has a roughly pillar-like form enclosed by a closed curve, and divided by said polymer network into areas whose minimum diameter measured by vernier calipers is 5 &mgr;m and whose maximum diameter measured by vernier calipers is 100 &mgr;m, is obtained by polymer networks formed by polymerization of monomer, so that sufficient reflection can be obtained from the liquid crystal without being optical scattering. Although the perpendicular array of the helical axes of liquid crystal is slightly disordered by a polymer network with respect to the plane of a pair of ITO , and substrates , , wherein since almost all light entering from the substrata side is reflected backwards (substrate side) by Bragg's reflection, it is possible to decrease the visual angle dependency in comparison with a prior art liquid crystal display not containing any polymer constituents, and networks which have been greatly established form intensive pillars (macromolcular resin walls), thereby improving the shock resistance properties.
