Abstract

See full text

In an active matrix type display apparatus which includes a first electrode substrate having a transparent insulation substrate on which a thin film transistor a transparent display pixel electrode selectively driven by the thin file transistor and a connecting portion for connecting the thin film transistor with the transparent display pixel electrode are formed, a second electrode substrate having another transparent insulation substrate on which an opposing electrode formed of a transparent conductive film is formed, and a display medium sandwiched between the first and second electrode substrates, an electrically conductive light shielding layer which is fixed at a predetermined potential is provided on each of thin film transistor portions of the first electrode substrate, and a part of the light shielding layer opposes a part of the transparent display pixel electrode through an insulation film so as to form a supplemental storage capacitor.
