Abstract
The present invention relates to methods of fabricating pixel electrodes (44) for active matrix displays including the formation of arrays of transistor circuits in thin film silicon (10) on an insulating substrate and transfer of this active matrix circuit onto an optically transmissive substrate (24). An array of color filter elements can be formed prior to transfer of the active matrix circuit that are aligned between a light source for the display and the array of pixel electrodes to provide a color display.
Claims10
An active matrix liquid crystal display comprising:
- an array of transistor circuits formed with a semiconductor layer on an insulating layer;
- a plurality of first and second contacts for each transistor;
- an array of pixel electrodes over regions on a first side of the insulating layer from which the semiconductor layer has been removed, each pixel electrode extending over the first contact of a transistor in each transistor circuit;
- a light shield over the array of transistor circuits with the transistor circuits interposed between the light shield and the first side of the insulating layer;
- and
- a liquid crystal material positioned on a second side of the insulating layer between the array of pixel electrodes and a counterelectrode.
