Claim 0:
1. A liquid crystal on silicon (LCOS) panel, comprising:
a first portion, comprising:
a backplane with an electrical contact and a plurality of pixel electrodes formed in the backplane; and
a first alignment layer disposed on the backplane and interfacing with the electrical contact;

a second portion, comprising:
a conductive layer that is light transmissive; and
a second alignment layer disposed on the conductive layer;

a plurality of spacer beads in a non-electrically-conductive adhesive,
wherein the non-electrically-conductive adhesive forms a wall between the first portion and the second portion, and the plurality of spacer beads defines a gap between the first portion and the second portion;

a liquid crystal fluid inside of the wall between the first portion and the second portion and surrounded by the wall,
wherein the plurality of pixel electrodes are aligned with the liquid crystal fluid; and

a plurality of beads in an electrically-conductive adhesive between the first portion and the second portion outside of the wall,
wherein the electrical contact is aligned with the plurality of beads,
wherein electrically-conductive particles within the electrically-conductive adhesive make the electrically-conductive adhesive electrically-conductive,
wherein sizes of the electrically-conductive particles are smaller than sizes of the plurality of beads,
wherein a first set of the electrically-conductive particles, aligned with one or more of the plurality of beads, puncture the first alignment layer to contact the electrical contact and a second set of the electrically-conductive particles, aligned with one or more of the plurality of beads, puncture the second alignment layer to contact the conductive layer, and
wherein an electrical connection of the electrical contact and the conductive layer is via a plurality of the electrically-conductive particles.
