Abstract:
The invention relates to a liquid crystal display element, a method of manufacturing the element, and electronic paper having the element. The invention provides a liquid crystal element in which a change in a state of display attributable to an external force can be suppressed, a method of manufacturing the element, and electronic paper having the element. One blue pixel region is surrounded by four wall structures and four polymer layers without any discontinuity. The wall structures are formed on a bottom substrate and are in contact with a top substrate. The polymer layers are formed by injecting a cholesteric liquid crystal and polymeric substances (monomers or oligomers) which are materials different from both of the cholesteric liquid crystal and the wall structures between the top and bottom substrates and polymerizing the polymeric substances.
