An electrooptical manufacturing apparatus is provided for manufacturing an electrooptical apparatus with an improved liquid crystal display quality. The apparatus basically includes a dam-forming section or apparatus, a droplet-ejecting section or apparatus, a seal-forming section or apparatus and a pressure applying section or apparatus. The dam-forming section is configured and arranged to form a dam that defines a liquid crystal area on the internal surface of a first substrate. The droplet-ejecting section is configured and arranged to eject and drop a specific amount of liquid crystal inside the dam. The seal-forming section is configured and arranged to form a seal that is disposed on the external periphery of the dam for sealing a second substrate disposed opposite the first substrate. The pressure applying section is configured and arranged to superpose and press in a vacuum atmosphere the second substrate onto the seal formed on the first substrate.
