Abstract
In an apparatus for adhering a polarizer to an LCD (Liquid Crystal Display) panel, a set plate for holding the panel thereon by suction is formed with a plurality of channels on the surface thereof. A discharge bar adjoins the set plate and blows air under pressure into the channels. When the panel is laid on or separated from the set plate, the air dissipates static electricity. This reduces electrostatic charge deposited on the panel and thereby reduces the electrostatic breakdown of the panel.
