In a driving circuit for a liquid crystal apparatus, a DC offset voltage the level of which changes depending upon the level of input video signals is applied as an input video signal. The DC voltage which appears in the liquid crystal and the level of which changes depending upon the level of input video signals can be completely compensated.

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.

An elastomer display system comprising a transparent silicon elastomer and electrodes for establishing a nonuniform electric field in the transparent silicon elastomer. Organic fluorescent centers are disposed within the transparent silicon elastomer. The electrodes are shaped in a desired configuration to ensure creation of the frost deformation in the transparent silicon elastomer when a predetermined voltage signal is applied to the electrodes. The frost deformation functions as a scattering center for the fluorescence derived from the organic fluorescent centers, thereby displaying a desired pattern.
