Abstract
An electro-optical device is manufactured by separately manufacturing an electronic component and an optical component and subsequently integrating the electronic and the optical components. Separate fabrication of the two components allows each component to be manufactured using processes which optimize its properties.
Claims34
A method of manufacturing an electro-optical device comprising:
- a) providing a modulating layer comprising a first substrate and an electro-optical material provided adjacent the first substrate, the modulating layer being capable of changing a visual state upon application of an electric field;
- b) providing a pixel layer comprising a second substrate, a plurality of pixel electrodes provided on a front surface of the second substrate and a plurality of contact pads provided on a rear surface of the second substrate, each pixel electrode connected to a contact pad through a via extending through the second substrate;
- c) providing a circuit layer comprising a third substrate and at least one circuit element;
- and
- d) laminating the modulating layer, the pixel layer and the circuit layer to form the electro-optical device.
