ABSTRACT:
A liquid crystal display device comprises a pair of substrates, a first patterned layer formed on a part of one of the substrates, a second layer formed on the remaining part of the one of the substrates, the thickness of the second layer being substantially identical to that of the first patterned layer to provide a layer uniform in thickness, and a third layer formed on the uniform layer to provide orientation of molecules of a liquid crystal layer disposed between the pair of substrates. The uniform layer is manufactured by the steps of forming the first patterned layer on part of the one of the substrates, and forming the second layer on the remaining part of the one of the substrates, using a lift-off method.
