An LCD device and a method of manufacturing the same are disclosed, in which a sealant concentrated upon the end of a dispensing device is formed in a dummy region on a substrate, so that a liquid crystal layer is not contaminated when both substrates are attached to each other and a cell cutting process can easily be performed. The method of manufacturing an LCD device includes preparing a lower substrate and an upper substrate, forming an auxiliary UV sealant in a dummy region on one of the lower and upper substrate and forming a main UV sealant, applying a liquid crystal on one of the lower and upper substrates, attaching the lower and upper substrates, and irradiating UV light onto the attached substrates.

Liquid crystal display device and method of manufacturing the same

A substrate bonding apparatus for use in fabricating LCD devices substantially prevents substrates held to upper stages from sagging. The substrate bonding apparatus may, for example, include upper and lower stages having a plurality of passages for holding respective substrates; suction force applying means having one end mounted within each passage for transmitting a suction force to operably proximate portions of a substrate, wherein the one end of the suction force applying means is projectable from within each passage to a predetermined distance from the stage; and a vacuum pump for providing a suction force to the suction force applying means.

Structure for loading substrate in substrate bonding apparatus for fabricating liquid crystal display device

An ink-jet printing apparatus that uniformly coats an alignment layer of an LCD device is provided. The ink-jet printing apparatus includes a head where the head has a head body and a supply pipe disposed inside the head body. The supply pipe allows the passage of a material through the head. The head also includes a nozzle and a foam removing means. The nozzle is in fluid communication with a portion of the supply pipe which discharges the material. The foam removing means is disposed in the nozzle and dissipates foam in the material.

A device for washing an inkjet head and an inkjet printing system having the same is provided. The device includes a bath which holds a washing solution and a wiping device disposed above the bath. The wiping device has a holding portion and an elastic wiper coupled with the holding portion. The elastic wiper is movable with respect to the holding portion, thereby permitting easy removal of alignment material from a nozzle on the inkjet head and cleaning of the elastic wiper.

Loader and bonding apparatus for fabricating a liquid crystal display device, and a loading method thereof are disclosed, the method for loading a substrate by using a loader having an arm with a plurality of robot fingers, and a plurality of adsorption pads on each of the robot fingers at regular intervals for adsorbing a substrate, and a bonding apparatus having a plurality of adsorption pins mounted on the upper stage movable in up/down direction for adsorption of the substrate being loaded, including the steps of the loader adsorbing, and holding the substrate at a back side thereof, and inverting the substrate, by using the adsorption pads, positioning the inverted substrate under the upper stage of the bonding apparatus, moving down the adsorption pins on the upper stage, and adsorbing the substrate at the back side thereof through the adsorption pins, removing adsorption force of the adsorption pads, and the loader being moved out of the bonding apparatus, and moving up the adsorption pins, and securing the substrate to the upper stage, whereby permitting inversion of the substrate without using an inverting device, and to prevent sagging of a large sized substrate to enable easy loading of the substrate on the bonding apparatus.

Loader and bonding apparatus for fabricating liquid crystal display device and loading method thereof

A liquid crystal display (LCD) device includes first and second substrates facing each other and having a display area and a non-display area, a sealant on a boundary between the display area and the non-display area to bond the first and second substrates, a first alignment layer on the display area of the first substrate, and a first dam in the display area of the first substrate inside the sealant to prevent spread of an alignment material of the first alignment layer.
