Patent ID: 7521272

Claim:
A method of manufacturing a display device, the display device comprising a display panel having a predetermined display area, the method comprising: a seal pattern forming step of forming a plurality of seal patterns each along an outer edge of a display area in each of a plurality of the display panels on at least one of a pair of facing surfaces of a first substrate and a second substrate facing each other; a position adjusting step of using a pair of surface plates having a pair of parallel surfaces on at least one of which a projected portion pattern with a planar shape corresponding to each of the plurality of seal patterns and a depressed portion pattern with a planar shape corresponding to a portion between the plurality of display panels adjacent to each other and a portion except for the seal patterns of the plurality of the display panels are formed to adjust positions of the first substrate and the second substrate between the pair of parallel surfaces so that the seal pattern coincides with the projected portion pattern; and a bonding step of bonding the first substrate and the second substrate arranged in the position adjusting step together through applying a first pressure to the first substrate and the second substrate in a direction vertical to the parallel surfaces by the pair of surface plates so as to have a predetermined space between the first substrate and the second substrate, and curing the seal pattern.
