Displays with Light-Curable Sealant

A method, comprising:

• forming a metal line on a first display substrate;
• forming a black masking layer on a second display substrate, wherein the black masking layer overlaps the metal line and has at least one opening;
• placing sealing adhesive between the first and second display substrates so that the sealing adhesive overlaps the metal line;
• and
• curing the sealing adhesive by applying ultraviolet light to the sealing adhesive through the at least one opening in the black masking layer.

A liquid crystal display having a periphery, comprising:

• a thin-film transistor layer having a substrate with at least one metal line;
• a color filter layer having a substrate with a black matrix layer, wherein the black matrix layer has at least one opening that overlaps the at least one metal line;
• a layer of liquid crystal material interposed between the thin-film transistor layer and the color filter layer;
• and
• ultraviolet-light-curable sealant this is interposed between the thin-film transistor layer and the color filter layer, wherein the ultraviolet-light-curable sealant surrounds the liquid crystal material and prevents leakage of the liquid crystal material at the periphery of the display, and wherein the at least one opening in the black matrix layer overlaps the ultraviolet-light-curable sealant.
