A substrate-chucking electrostatic chuck (ESC) is disclosed which is sub-divided into at least three groups of electrostatic blocks, to uniformly chuck the substrate. A substrate bonding apparatus and method for a liquid crystal display (LCD) panel using the electrostatic chuck is also disclosed. The ESC includes at least three groups of electrostatic blocks which chuck the substrate using electrostatic chucking forces respectively generated by different voltages applied to the electrostatic blocks in association with the electrostatic block groups, and release the chucked substrate when the voltages are cut off.

Substrate-chucking electrostatic chuck, and substrate bonding apparatus and method for liquid crystal display panel using the same

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

A substrate bonding apparatus for a liquid crystal display (LCD) panel is disclosed that subdivides its venting holes, thereby achieving an enhancement in uniformity of venting. The substrate bonding apparatus that bonds a first substrate and a second substrate using a venting process, includes a lower chucking plate which chucks the second substrate, and an upper chucking plate which includes a plurality of blocks each including a main venting hole, wherein the upper chucking plate chucks the first substrate in accordance with a chucking operation of the blocks, and subsequently releases the chucked first substrate such that the first substrate falls down toward the second substrate.
