Abstract
Provided are a manufacturing method which can efficiently manufacture a display device with higher image quality, and a manufacturing apparatus which can be applied to the manufacturing method. Position adjustment is carried out so that a seal pattern () formed on at least one of a bottom substrate () and a top substrate () and having a shape along an outer edge of each of a plurality of display panels () coincides with a projected portion pattern () () formed on at least one of a pair of parallel surfaces (S) (S) in a bottom surface plate () and a top surface plate () and having a planar shape corresponding to the seal pattern (), and pressure is applied to the bottom substrate () and the top substrate () in a Z direction by the bottom surface plate () and the top surface plate (). Therefore, a gap between the bottom substrate () and the top substrate () in an effective screen area () can be formed more uniformly, and a display device with higher image quality can be efficiently manufactured.
