ABSTRACT:
An active matrix structure for display screen includes a storage capacitor bus disposed under each row of pixel electrodes, produced in a transparent conducting material, and disposed in the structure on a level separated from a level of the row selection lines and a level of the pixel electrodes by an insulation layer at least. The storage bus of a row is driven by a selection line of a previous row.
