Disclosed is a method for manufacturing a display panel, which employs a vacuum bonding method. A display material is dispensed such that the height distance from the upper surface of a lower substrate to the top of the display material is larger than the height distance from the surface of either upper or lower substrate on which the seal pattern is formed to the apex of the seal pattern. The upper substrate is placed at a position where the upper substrate and the top of the display material in the height direction are in touch with each other and the seal pattern on one substrate is not in touch with the other substrate, then, air is released. Thus, volatilization of the display material is reduced easily at small cost to prevent drying of the surface of the display material, and the display qualities can be prevented from being degraded.
