Claim 2

A method of manufacturing a liquid crystal element, wherein a liquid crystal layer is interposed between a pair of planar substrate members, at least one of which has light-shielding means, comprising the steps of: (a) forming an electroconducting layer on a surface of an insulating substrate defining one of the planar substrate members; (b) applying a resist to the surface of the electroconducting layer; (c) exposing the resist to light using a mask having a predetermined pattern; (d) developing the exposed resist; (e) removing portions of the electroconducting layer, bared by developing the resist, to form electrodes in the predetermined pattern; (f) forming, by the use of an electrodeposition method, light-shielding means, extending from an electrode side-surface perpendicular to the planar insulating substrate in a direction parallel to the insulating substrate; and (g) removing all of the resist on the electrodes.

Claim 3

A method of manufacturing a liquid crystal element, wherein a liquid crystal layer is interposed between a pair of planar substrate members, at least one of which has a light-transmitting property and both of which have light-shielding means and which define an X-Y plane,, comprising the steps of: (a) forming an electroconducting layer on a surface of an insulating one of said planar substrate members; (b) applying a resist to the surface of the electroconducting layer; (c) exposing the resist to light using a mask having a predetermined pattern of a plurality of stripes in parallel to one another; (d) developing the exposed resist; (e) removing, in a Z-direction, portions of the electroconducting layer, bared by developing the resist, to form electrodes in the predetermined pattern; (f) forming, by the use of an electrodeposition method, light-shielding means, extending from an electrode side-surface perpendicular to the planar insulating substrate in a direction parallel to the insulating substrate; and (g) removing all of the resist on the electrodes; (h) forming an alignment layer enveloping the electrodes and the light-shielding means in order to form a substrate member; (i) bonding a pair of substrate members, manufactured in the above manner, leaving a predetermined space therebetween, so that the alignment layers thereof are facing each other, and the electrodes thereof are in said X-Y plane and are right-angled with respect to each other; and (j) injecting a liquid crystal between the pair of substrate members.
