placed between a pair of substrates
101
and
102
, at least one of which is transparent, liquid crystal layer
110
′ sealed between the alignment layers, common electrode
103
and source electrode
105
for applying an electrical field to the liquid crystal layer, thin-film transistors connected to each of these electrodes, polarizer plate
114
provided on at least one of the substrates, wherein at least one of the alignment layers
109
is composed of a photo-reactive polyimide and/or polyamic acid which can be provided with a liquid crystal alignment capacity by being irradiated with essentially linearly polarized light.
