Abstract

A pixel circuit is disposed in correspondence to an intersection of a scanning line and a data line. The pixel circuit is provided with a wiring for shielding an relay electrode connected to a source of the transistor for controlling a current flowing to a light emitting element from the data line. The wiring has a structure in which an relay electrode located on the same layer as the data line, an relay electrode located on the same layer as the relay electrode, an electrode portion of a conductive layer between the data line and the relay electrode are electrically connected to each other.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An electro-optical device comprising:
 a scanning line;   a data line;   a feed line;   a driving transistor supplying a current according to a voltage between a gate and a source to the source from a drain,   a switching transistor electrically connected between the gate of the driving transistor and the data line,   a first capacitor having a first dielectric film disposed between a first electrode electrically connected to the source of the driving transistor and a second electrode electrically connected to the gate of the driving transistor;   a light emitting element having an anode which is electrically connected to the source of the driving transistor, and emitting light according to the current flowing from the anode to a cathode, and   a second capacitor having a second dielectric film disposed between the first electrode and a third electrode electrically connected to the feed line,   wherein at least part of the third electrode is overlapped with the second electrode.   
     
     
         2 . The electro-optical device according to  claim 1 ,
 wherein the first electrode is disposed between the driving transistor and the switching transistor.   
     
     
         3 . The electro-optical device according to  claim 1 , further comprising a power line electrically connected to the drain of the driving transistor. 
     
     
         4 . The electro-optical device according to  claim 3 ,
 wherein the driving transistor is disposed between the first electrode and the power line.
