Display Panel and Manufacturing method thereof

Abstract

A display panel includes a first substrate that has a first display area in which signal lines are formed, a second substrate that has a second display area corresponding to the first display area of the first substrate, and a sealant that is used to bond the first substrate and the second substrate and at least a portion of which is formed in either of the first display area of the first substrate and the second display area of the second substrate.

What is claimed is: 
     
         1 . A manufacturing method of a display panel comprising the steps of:
 preparing a first substrate that has a first display area in which signal lines are formed;   preparing a second substrate that has a second display area corresponding to the first display area of the first substrate;   applying a sealant on at least one of the first display area of the first substrate and the second display area of the second substrate;   aligning the first substrate and the second substrate such that the first display area faces the second display area and bonding the first substrate and the second substrate; and   cutting the bonded first and second substrates such that the sealant is positioned inside.   
     
     
         2 . The manufacturing method according to  claim 1 , wherein the display panel is selected from the group consisting of a display panel of a liquid crystal display (LCD), a display panel of a field emission display (FED), a display panel of a plasma display panel (PDP), a display panel of an electroluminescence device (ELD), a display panel of an electrophoresis display (EPD), and a display panel of a flexible display. 
     
     
         3 . The manufacturing method according to  claim 2 , wherein the sealant is formed in a closed loop type or in an open loop type wherein a portion of the loop is open. 
     
     
         4 . The manufacturing method according to  claim 2 , further comprising injecting liquid crystal between the cut first and second substrates and sealing the liquid crystal. 
     
     
         5 . The manufacturing method according to  claim 2 , wherein the sealant overlaps with at least one of the signal lines which are formed in the first display area of the first substrate.
