Display apparatus and fabrication method for display apparatus

Abstract

Disclosed herein is a display apparatus, including: a plurality of pixel circuits arrayed in a matrix; a driving wiring line to which the pixel circuits are connected; and a plurality of signal lines wired so as to cross with the driving wiring line and having the pixel circuits connected; the signal lines being wired in parallel to each other.

What is claimed is: 
     
         1 . A display apparatus, comprising:
 a plurality of pixel circuits arranged in a matrix;   a driving wiring line configured to supply a driving pulse to the plurality of pixel circuits; and   a potential line configured to supply one of video data and a predetermined voltage to the plurality of pixel circuits,   wherein the potential line includes a main line and an auxiliary line that is parallel to the main line, and the main line and the auxiliary line are connected to each other by connecting wiring lines, and   wherein the main line and the auxiliary line are connected in a ladder configuration.   
     
     
         2 . The display apparatus according to  claim 1 , wherein the potential line alternately supplies one of the video data and the predetermined voltage to the plurality of pixel circuits. 
     
     
         3 . The display apparatus according to  claim 1 , wherein the main line and the auxiliary line are disposed extending in a column direction. 
     
     
         4 . The display apparatus according to  claim 1 , wherein the main line and the auxiliary line are disposed on one side of a column of the plurality of pixel circuits. 
     
     
         5 . The display apparatus according to  claim 1 , wherein the connecting wiring lines are disposed extending in a row direction. 
     
     
         6 . The display apparatus according to  claim 1 , wherein the connecting wiring lines are substantially parallel to each other. 
     
     
         7 . The display apparatus according to  claim 1 , wherein the main line and the auxiliary line are connected to each other at a first position and a second position. 
     
     
         8 . The display apparatus according to  claim 7 , wherein, where one of the plurality of pixel circuits which is to be connected is defective, the main line is cut at a first predetermined position between the first position and a defect position and at a second predetermined position between the second position and the defect position, whereby the main line between the first and second positions is replaced with the auxiliary line.
