Display device and electronic apparatus

Abstract

A display device includes an anode electrode provided for each pixel, an opening insulation film which covers the periphery of the anode electrode and which defines an pixel opening, and a storage capacitor disposed below the anode electrode through a planarizing insulation film, having a function to store charge for driving a pixel, and including capacitor electrodes wider than the pixel opening.

What is claimed is: 
     
         1 . A display device comprising:
 a plurality of pixels;   a display electrode provided for each of the pixels;   an opening insulation film which covers the periphery of the display electrode and which defines a pixel opening; and   a storage capacitor disposed below the display electrode; and   a planarizing insulation film disposed between the display electrode and the storage capacitor and which stores charge for driving the corresponding pixel,   wherein,
 the display electrode is wider than the pixel opening, and 
 at least a portion of the storage capacitor is wider than the pixel opening. 
   
     
     
         2 . The display device according to  claim 1 , wherein the display electrode is wider than at least a portion of the storage capacitor. 
     
     
         3 . The display device according to  claim 1 , wherein the storage capacitor comprises a pair of capacitor electrodes, each of which has a portion wider than the pixel opening. 
     
     
         4 . The display device according to  claim 3 , wherein at least the capacitor electrode nearest to the display electrode has a shape corresponding to the shape of the pixel opening. 
     
     
         5 . The display device according to  claim 3 , wherein at least the capacitor electrode nearest to the display electrode has substantially the same width as that of the pixel opening. 
     
     
         6 . An apparatus comprising a display device mounted on a body casing, wherein:
 the display device includes (a) a plurality of pixels, (b) a display electrode provided for each of the pixels, (c) an opening insulation film which covers the periphery of the display electrode and which defines an pixel opening, (d) a storage capacitor disposed below the display electrode, and (e) a planarizing insulation film disposed between the display electrode and the storage capacitor and which stores charge for driving the corresponding pixel;   the display electrode is wider than the pixel opening; and   at least a portion of the storage capacitor is wider than the pixel opening.   
     
     
         7 . The apparatus according to  claim 6 , wherein the display electrode is wider than at least a portion of the storage capacitor. 
     
     
         8 . The apparatus according to  claim 6 , wherein the storage capacitor comprises a pair of capacitor electrodes, each of which has a portion wider than the pixel opening. 
     
     
         9 . The apparatus according to  claim 8 , wherein at least the capacitor electrode nearest to the display electrode has a shape corresponding to the shape of the pixel opening. 
     
     
         10 . The apparatus according to  claim 8 , wherein at least the capacitor electrode nearest to the display electrode has substantially the same width as that of the pixel opening.
