  • Method for adjusting amount of liquid crystal in an LCD device including reducing the thickness of a seal member to form a repair region by laser heating a metal pattern thereunder
    Patent number: 8988646
    Abstract: 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 a liquid crystal display (LCD) device further includes reducing a thickness of the sealing member at a predetermined portion of the sealing member to form a repair region, and pressurizing the liquid crystal to break the sealing member at the repair region to discharge some of the liquid crystal from the liquid crystal receiving space, so as to adjust the amount of the liquid crystal in the liquid crystal receiving space. The method for adjusting an amount of liquid crystal in a liquid crystal display (LCD) device also includes resealing the broken repair region of the sealing member.
