ABSTRACT:
An active element on an insulating substrate of an electro-optical display device includes a layer of ferroelectric material as an active layer between two electrodes for each pixel in the display. The active device includes a first electrode formed on an insulating substrate, the ferroelectric layer covering the first electrode and the insulating substrate, and the second electrode disposed on the ferroelectric layer for overlapping a portion of the first electrode with the ferroelectric material therebetween. Preferably, the ferroelectric material is an organic ferroelectric material.
