US Patent 7609359 Method of manufacturing liquid crystal panel

A plurality of projections are formed on one of a pair of substrates in a manner to surround a display area, thereafter a mask for shielding the outside of the display area on the substrate is placed such that the mask is in contact with the projections, and a deposition film is deposited within the display area with the mask being placed. After the mask is removed, a sealing material is placed in a region where the projections are formed. Then, another substrate of the pair of substrates is placed opposed to the one substrate having the projections formed thereon.
