Abstract:
A liquid crystal display device, comprising:a pair of substrates;a liquid crystal layer interposed between the pair of substrates; andan electrode for applying a voltage to the liquid crystal layer,wherein the liquid crystal layer includes a polymer dispersed liquid crystal material having a polymer phase and a liquid crystal phase, and fulfills the conditions represented by:R.multidot..DELTA.n>0.3 and 8R<dwherein d represents the thickness of the liquid crystal layer in the unit of micrometers, R represents the characteristic length of the liquid crystal phase in the unit of micrometers, and .DELTA.n represents the birefringence of a liquid crystal material forming the liquid crystal phase, wherein the liquid crystal phase fulfills the conditions represented by:R.multidot..DELTA.n>0.35 and d<1.2dcwherein dc represents a minimum thickness of the liquid crystal layer which allows a scattering gain of the liquid crystal layer to change by 20% or less when the thickness of the liquid crystal layer changes by 10%.
