Abstract

Disclosed herein is a display apparatus including first and second substrates, at least one of which has a light transmitting characteristic, as well as first and second electrodes provided on the two mutually facing surfaces of the first and second substrates respectively; and an electrophoretic device provided between the first and second substrates, wherein the first substrate and the first electrode each have an external edge folded back so as to cover at least a portion of a terminal surface of the second substrate.

What is claimed is: 
     
         1 . A display apparatus comprising:
 first and second substrates, at least one of which has a light transmitting characteristic, as well as first and second electrodes respectively provided on a first surface and a second surface of said first and second substrates, the first surface and the second surface facing each other; and   a display element provided between said first and second substrates,   wherein said first substrate and said first electrode each have an external edge folded back so as to cover at least a portion of a terminal surface of said second substrate.   
     
     
         2 . The display apparatus according to  claim 1 , wherein said external edge of said first electrode is connected to a third electrode provided on said second substrate. 
     
     
         3 . The display apparatus according to  claim 2 , wherein said external edge of said first substrate and said external edge of said first electrode are folded back so as to cover at least a portion of the back surface of said second substrate. 
     
     
         4 . The display apparatus according to  claim 3 , wherein said third electrode is provided on said back surface of said second substrate. 
     
     
         5 . The display apparatus according to  claim 2 , wherein:
 said first electrode is a common electrode shared by a plurality of pixels;   said second electrode is a plurality of pixel electrodes each created for one of said pixels; and   said third electrode is a driving electrode for determining an electric potential of said first electrode.   
     
     
         6 . The display apparatus according to  claim 1 , wherein said electrophoretic device is created to be exposed to said entire mutually facing surface of said second substrate. 
     
     
         7 . The display apparatus according to  claim 1 , said display apparatus further comprising:
 a plurality of first signal lines and a plurality of second signal lines in a space between said second substrate and said second electrode, wherein   said first signal lines and said second signal lines intersect each other, and   at least one end of each of said first signal lines and at least one end of each of said second signal lines are folded back from said terminal surface of said second substrate to said back surface of said second substrate.   
     
     
         8 . The display apparatus according to  claim 1 , wherein a signal processing circuit for supplying signals to said first signal lines and said second signal lines is provided on the back surface of said second substrate. 
     
     
         9 . The display apparatus according to  claim 1 , wherein a signal processing circuit for supplying signals to said first signal lines and said second signal lines is provided on the upper surface of said second substrate. 
     
     
         10 . The display apparatus according to  claim 1 , wherein said electrophoretic device includes a multi-hole structural body containing a plurality of electrophoretic particles and a plurality of non-electrophoretic particles each having an optical reflection characteristic different from that of each of said electrophoretic particles in an insulating liquid unit.
