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.

LCD device including a repair region with a metal pattern capable of being burnt down

Disclosed herein are a liquid crystal display (LCD) device and a method for manufacturing the same, capable of preventing problems (i.e., movement of balls, damage to the surfaces that face spacers upon application of predetermined pressure, and variation in cell gap) associated with the use of the ball spacers. The liquid crystal display device includes a first substrate and a second substrate facing each other, a spacer formed on the first substrate, wherein the spacer includes a plurality of balls and a solid to aggregate the balls together and adhere the balls to the first substrate, a hard coating layer formed on the second substrate facing the spacer, and a liquid crystal layer filled between the first substrate and the second substrate.

Liquid crystal display and method for manufacturing the same

A color filter substrate for a liquid crystal display device and a method of fabricating the same includes black matrixes on a transparent insulating substrate, the black matrixes defining pixel areas and having a first region and a second region, color filters in the pixel areas and having areas overlapping the first region of the black matrixes, and ball spacers above the second region of the black matrixes, wherein a thickness of the first region is greater than a thickness of the second region.

An LCD device and a method for manufacturing the same is disclosed, in which it is possible to correct a problem of insufficient or excessive supply of liquid crystal in an LCD device by controlling an amount of liquid crystal. The method includes preparing a liquid crystal cell comprised of a first substrate, a second substrate, a liquid crystal layer between the first and second substrates, and a first sealant formed in the periphery of the liquid crystal layer between the first and second substrates; measuring an amount of liquid crystal provided to the inside of liquid crystal cell; forming an inlet for liquid crystal in the first sealant; and regulating the amount of liquid crystal by supplying or discharging the liquid crystal through the inlet; and sealing the inlet.

Methods of manufacturing liquid crystal display devices

An apparatus for coating a polyimide layer includes a printing table in which a substrate is provided, an inkjet head having an injection surface with nozzles for injecting a polyimide liquid onto the substrate, a polyimide liquid supply tank filled with the polyimide liquid, an ultrasonic cleaner in which a cleaning liquid for cleaning the inkjet head is stored for cleaning the inkjet head with vibrations in the cleaning liquid generated by applying an ultrasonic signal, and a wiper for wiping an injection surface of the inkjet head.

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.
