LIQUID CRYSTAL DISPLAY
A liquid crystal display including: a first substrate on which a first electrode and a first orientation layer are formed; a second substrate facing the first substrate and including a second electrode and a second orientation layer; a sealant formed along edges of the first substrate and the second substrate; and a liquid crystal layer between the first electrode and the second electrode; wherein holes are formed in the first and second orientation layers and the sealant is bonded to the first and second subatrates through both side holes. Since a contact area between the sealant and the substrates is increased and a bonding force is improved, a stable sealing state can be maintained with a small area and a size of a non-pixel region is reduced so that a small-sized liquid crystal display can be achieved.

wherein holes are formed in the first and second orientation layers and the sealant is bonded to the first and second subatrates through both side holes.
2 . The liquid crystal display as claimed in claim 1 , wherein the holes are arranged alternately.
3 . The liquid crystal display as claimed in claim 1 , wherein the holes are rectangular or circular.
4 . The liquid crystal display as claimed in claim 1 , wherein the holes are smaller than a size of a unit pixel of the liquid crystal display.
