A display device has a plurality of pixels, each having a current-driven
display element coupled between a first conductive layer and a second
conductive layer, the second conductive layer being coupled to a current
supply via a switchable device having a thin film component on a first
area of a substrate. Each pixel has a first capacitive device having a
first capacitor plate on a second area of the substrate, the first
capacitor plate conductively coupled to the thin film component, a second
capacitor plate and a first insulating layer between the first capacitor
plate and the second capacitor plate. On top of the first capacitive
device is a second capacitive device sharing the second capacitor plate,
the second capacitive device including a third capacitor plate sharing
the second conductive layer, and a second insulating layer between the
second capacitor plate and the third capacitor plate.
