Display device using bidirectional two-terminal element and manufacturing method thereof

A method of manufacturing a display device comprising the steps of:

• (a) forming on a principal surface of a substrate a plurality of first electrodes having an electrode layer with an opening formed therein;
• (b) preparing a plurality of bidirectional two-terminal elements, each of the plurality of bidirectional two-terminal elements having a pair of mutually opposed electrodes;
• (c) placing said plurality of bidirectional two-terminal elements on said plurality of first electrodes so that each of the plurality of bidirectional two-terminal elements is electrically connected to at least one of said plurality of first electrodes via one of said pair of electrodes;
• (d) forming a plurality of picture electrodes electrically connected to at least one of said plurality of first electrodes via at least one of said plurality of bidirectional two-terminal elements, respectively;
• and
• (e) providing a plurality of second electrodes and a display medium layer to be mutually opposed between said plurality of picture electrodes and said plurality of second electrodes via said display medium layer.

An active matrix substrate comprising:

• a plurality of first electrodes;
• a plurality of picture electrodes electrically connected to at least one of said plurality of first electrodes via at least one bidirectional two-terminal element, respectively;
• a plurality of second electrodes;
• and
• a display medium layer provided between said plurality of picture electrodes and said plurality of second electrodes;
• wherein each of said plurality of first electrodes has an electrode layer having an opening formed at least in a portion of an area overlapping said plurality of picture electrodes.
