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.

Claims (17)

1. A display device comprising:

a plurality of pixels;

a display electrode provided for each pixel;

an opening insulation film for each pixel which covers the periphery of the display electrode and which defines a pixel opening;

a storage capacitor for each pixel disposed below the display electrode; and

a planarizing insulation film for each pixel between the display electrode and the storage capacitor,

wherein,

the storage capacitor stores charges for driving the pixel,

the storage capacitor includes a pair of capacitor electrodes, one of which has a portion wider than the pixel opening,

at least the capacitor electrode nearest to the display electrode has a shape corresponding to the shape of the pixel opening, and

at least the capacitor electrode nearest to the display electrode has substantially the same width as that of the pixel opening.

2. An electronic 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 pixel, (c) an opening insulation film for each pixel which covers the periphery of the display electrode and which defines a pixel opening, (d) a storage capacitor for each pixel which is disposed below the display electrode, and (e) a planarizing insulation film for each pixel between the storage capacitor and the display electrode;

the storage capacitor stores charges for driving the pixel,

the storage capacitor includes a pair of capacitor electrodes, one of which is wider than the pixel opening,

at least the capacitor electrode nearest to the display electrode has a shape corresponding to the shape of the pixel opening, and

at least the capacitor electrode nearest to the display electrode has substantially the same width as that of the pixel opening.
