Abstract
In an antiferroelectric liquid crystal panel, in which a plurality of strip-shaped first and second transparent electrodes are formed on a pair of first and second substrates, the substrates are opposedly disposed so that the transparent electrodes intersect with each other at right angles, and the antiferroelectric liquid crystal is filled in a gap thereinbetween, at least at the positions corresponding to intersecting portions of the gaps between a plurality of first transparent electrodes and the gaps between a plurality of second transparent electrodes. Spacers are fixed on the first substrate and made of insulating material, a first alignment layer is formed to cover at least the first transparent electrodes on the first substrate, and a second alignment layer is formed to cover the second transparent electrodes on the second substrate.
