Display panel assembly apparatus for assembling a display panel by bonding a driver substrate onto a glass panel via a connector and bonding material. A panel positioning table retains the glass panel in which the connector is bonded to its edge, and positions the glass panel with respect to a bonder from one side. The substrate to which a bonding tape is applied by a bonding tape applicator is transferred to the bonder from the other side by circulating a substrate holder on which the substrate is placed using a circulatory transport mechanism. The connector prebonded on the glass panel and the substrate are then bonded via the bonding tape. Adoption of this configuration for the display panel assembly apparatus and assembly method reduces the apparatus installation area while achieving high productivity.
