Disclosed are a substrate support apparatus and an apparatus for examining the seal pattern of an LCD cell. The substrate support apparatus includes a movable stage provided with drawing nozzles for attaching a substrate to an upper surface and adapted to rotate by a predetermined angle; a fixed stage spaced from the movable stage and provided with floating nozzles for ejecting air upward and drawing nozzles for drawing air downward; and a driving device coupled to the movable stage to rotate the movable stage. The apparatus for examining the seal pattern of an LCD cell includes the substrate support apparatus; and a gantry unit including support platforms positioned on both sides of the substrate support apparatus, a bridge positioned above the substrate support apparatus to connect the support platforms, and a correction device coupled to the bridge to examine and repair a seal pattern of a substrate.
