Zusammenfassung:An apparatus for removing sealant on an LCD panel is provided to prevent a scratch on the surface of the LCD panel by a knife when the knife removes the projected sealant on the surface of the LCD panel, thereby improving the reliability of process by preventing the damage of the LCD panel. An apparatus for removing sealant on an LCD panel comprises upper and lower support members(210,310), an upper holder(220), a lower holder(320), an elastic support unit(350), and a panel support unit(400). The upper and lower support members move respectively up and down by the driving of upper and lower knife driving units(M1,M2) installed in a main body(100). The upper holder has an upper knife(240), which is detachably attached to remove the sealant projected to the upper surface of the LCD panel, and is joined to the upper support member. The lower holder has a lower knife(340), which is detachably attached to remove the projected sealant on the lower surface of the LCD panel, and is joined to the lower support member. The elastic support unit is joined between the lower support member and the lower holder to support the lower holder elastically. The panel support unit is joined to the main body movably up and down and supports selectively the upper surface of the panel.
