Abstract
A liquid crystal display device which includes a liquid crystal layer formed between a pair of polymer film substrates. A pair of polarizing plates are formed on outer surfaces of each of the substrates. Moreover, a thickness of each of the substrates D (&mgr;m) and a thickness of each of the polarizing plates L (&mgr;m) satisfy D=L±30 &mgr;m. A thickness of protecting layers forming each polarizing plate may be 50 &mgr;m or less and a thickness of a polarizer of a polarizing plate may be 20 &mgr;m. A cohesive layer may be provided to attach each polarizing plate to the liquid crystal device, and such a cohesive layer may have a thickness of at least 50 &mgr;m. A spacer layer can be provided in conjunction with the cohesive layer.
