Abstract
A liquid crystal display device has at least a pair of transparent substrates, polymer-stabilized blue phase liquid crystal layer disposed therebetween, and a transparent film having an absolute value |Re| of in-plane retardation Re of 10 nm or smaller in the visible light region, having an absolute value |Rth| of thickness-wise retardation Rth of 30 nm or smaller in the visible light region, having an absolute value |Re(400)−Re(700)| of difference between values of in-plane retardation Re at 400 nm and 700 nm of 10 nm or smaller, and having an absolute value |Rth(400)−Rth(700)| of difference between values of thickness-wise retardation Rth at 400 nm and 700 nm of 35 nm or smaller.
