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.

1 . A display apparatus, comprising:
 a plurality of pixel circuits configured to form a matrix;   a plurality of driving wiring lines configured to connect the plurality of pixel circuits;   a plurality of signal lines configured to cross the plurality of driving wiring lines and to connect the plurality of pixel circuits; and   a plurality of power supply lines configured to connect the plurality of pixel circuits, wherein   the plurality of power supply lines are formed in a two-stage wiring structure including a first wiring layer and a second wiring layer,   the first wiring layer is formed in a same layer of the plurality of driving wiring lines and is disposed on a first insulating film,   a contact hole is formed in a second insulating film formed on the first wiring layer,   the second wiring layer is formed on the second insulating film and is connected to the first wiring layer through the contact hole, and   a flattening film is formed on the second wiring layer.   
     
     
         2 . The display apparatus according to  claim 1 , wherein an anode electrode is disposed on the flattening film. 
     
     
         3 . The display apparatus according to  claim 2 , wherein the anode electrode and the second wiring layer are connected by the contact hole. 
     
     
         4 . The display apparatus according to  claim 1 , wherein the plurality of power supply lines comprise low-resistance wiring lines of a same material. 
     
     
         5 . The display apparatus according to  claim 4 , wherein the same material is aluminum.
