Patent number: 7724346Abstract: A method for adjusting an amount of liquid crystal in a liquid crystal display (LCD) device includes injecting a liquid crystal into a liquid crystal receiving space. The liquid crystal receiving space is disposed between a first substrate, a second substrate that faces the first substrate, and a sealing member interposed between the first and second substrates. The method for adjusting an amount of liquid crystal in an LCD device further includes irradiating a light to a portion of the sealing member while varying an irradiating angle of the light so as to form a repair region at the sealing member that has a thickness smaller than that of the sealing member. The method for adjusting an amount of liquid crystal in an LCD device also comprises pressurizing the liquid crystal to form an opening in the repair region of the sealing member and discharge some of the liquid crystal from the liquid crystal receiving space through the opening formed in the repair region, and sealing the opening of the repair region.Type: GrantFiled: December 7, 2006Date of Patent: May 25, 2010Assignee: LG.
