A constitution of the display device of the invention is shown in the
following. The display device includes a pixel unit including TFTs of
which the active layer contains an organic semiconductor material for
forming channel portions in the opening portions in an insulating layer
arranged to meet the gate electrodes. The pixel unit further includes a
contrast media formed on the electrodes connected to the TFTs for
changing the reflectivity upon the application of an electric field, or
microcapsules containing electrically charged particles that change the
reflectivity upon the application of an electric field. The pixel unit is
sandwiched by plastic substrates, and barrier layers including an
inorganic insulating material are provided between the plastic substrates
and the pixel unit. The purpose of the present invention is to supply
display devices which are excellent in productivity, light in weight and
flexible.
