Active matrix optical device

A method of manufacturing an active matrix organic optical device comprising forming a plurality of organic thin film transistors comprising, organic semi-conductive material and a plurality of pixels comprising organic optically active material on a common substrate, wherein a common bank layer is provided for the organic thin film transistors and the pixels, the common bank layer defining a plurality of wells, wherein some of the wells contain organic semi-conductive material of the organic thin film transistors therein and others of the wells contain the organic optically active material of the pixels therein,

• forming insulative separator structures on top of the bank layer;
• and
• depositing a top electrode layer over the entire active surface of the active matrix organic optical device and insulative separator structures such that the electrical continuity between the top electrode layer covering the organic thin film transistors and that covering the pixels is broken by the presence of the insulative separator structures to electrically isolate the organic thin film transistors from the pixels on a top side of the active matrix organic optical device.
