Claim Text:
1. A liquid crystal cell, comprising: a first substrate; a first overcoat layer being formed on a surface of the first substrate, wherein the first substrate comprises a first region and a second region; a barrier layer being formed on a surface of the first overcoat layer in the first region; a second substrate bonded with the first substrate; a first spacer being formed on a surface of the second substrate facing the first substrate, wherein the first spacer is aligned with the first region; a second spacer being formed on the surface of the second substrate facing the first substrate, wherein the second spacer is aligned with the second region, wherein the length of the first spacer is greater than or equal to the length of the second spacer; and a liquid crystal layer formed between the first substrate and the second substrate, wherein the surface area of a lower surface of the barrier layer is greater than the surface area of a lower surface of the first spacer; and wherein the material of the barrier layer is a transparent metal or an oxide of the transparent metal.
