A liquid crystal display device is provided with a pair of substrates which are
arranged to face each other in an opposed manner and a liquid crystal layer which
is sandwiched between main surfaces of a pair of substrates. On the main surface
of one of the pair of substrates which faces the liquid crystal layer, pixel regions
including switching elements, pixel electrodes which are connected to the switching
elements and a protective film which is disposed at liquid crystal layer side of
the switching elements are formed. In such a liquid crystal device, the protective
film is formed by laminating the plurality of material layers which include at
least a first material layer and a second material layer which is arranged closer
to the liquid crystal layer side than the first material layer. Further, the second
material layer exhibits resistivity which is lower than resistivity of the first
material layer and higher than resistivity of silicon or semiconductor layers which
constitute channels of the switching elements. Due to such a constitution, the
image retention which is generated on a display screen of the liquid crystal display
device can be reduced.
