Claims17
A structure for making a display that forms images comprising:
- a) a transparent substrate having first and second surfaces;
- b) a light sensitive conductive layer provided over the first surface of the transparent substrate and patternable to form conductive traces;
- and
- c) means provided over the second surface defining an array which can produce a colored image.

Apparatus forming a display comprising:
- a) a transparent first substrate having first and second surfaces;
- b) first patterned conductive traces formed by light patterning and provided over the first surface of the transparent substrate;
- c) a color forming array provided over the second surface;
- d) a second transparent substrate having top and bottom surfaces and second conductive traces formed over its top surface;
- e) a layer including a light modulating material being provided between the bottom surface of the second transparent substrate and the second surface of the first transparent substrate;
- and
- f) the first and second conductive traces being aligned so that when a potential is applied between them, a field is produced which operates upon the light modulating material layer to selectively transmit light which passes through the second transparent substrate, the light modulating layer, the second transparent substrate, and the color filter array so that a displayed image is produced.

A method of making a display apparatus comprising the steps of:
- a) providing a transparent first substrate having first and second surfaces;
- b) layer a patternable conductive layer on the First surface and patterning such layer to provide conductive traces formed over the first surface of the transparent substrate;
- c) forming a color filter array over the second surface;
- d) providing a second transparent substrate having top and bottom surfaces;
- e) providing second conductive traces aligned with the first conductive traces formed over the top surface of the second transparent substrate;
- f) layer a layer including a light modulating material between the bottom surface of the second transparent substrate and the second surface of the first transparent substrate;
- and
- g) applying potential between the aligned first and second conductive traces so that a field is produced which operates upon the light modulating material layer to selectively transmit light which passes through the second transparent substrate, the light modulating layer, the second transparent substrate, and the color filter array so that a displayed image is produced.
