Abstract
There is disclosed a method for producing an electro-optical device applied as image display device. This method comprises the steps of forming a plurality of channels on a major surface of a first substrate, each of the channels being substantially in parallel to each other; forming first electrodes in each channel; filling the channels with a material so as to flatten the major surface of the first substrate; depositing a dielectric layer on the flattened surface of the first substrate; removing the filled material from the channels; and combining the first substrate with second substrate, the second substrate having a plurality of second electrodes substantially perpendicular to the channels in an inner surface of the first substrate, and an electro-optical material layer interposed between the dielectric layer and the second substrate. An employment of this producing method results in no restriction in the thickness or dimension of a dielectric sheet, thus making it possible to provide an image display device free from the problem of unevenness in thickness thereof.
