Abstract: A display apparatus includes an enhanced sealing portion. The display apparatus includes a substrate unit that includes a first substrate and a second substrate facing each other; a sealing portion that is disposed between the first substrate and the second substrate; and a metal film that is disposed between the first substrate and the sealing portion. Open holes having different sizes are formed in proportion to energy intensities of an energy source applied to the metal film. During sealing in a sealing region by using a laser, since the metal film having a specific shape is patterned, even when energy having an irregular Gaussian shape is applied, uniform energy may be applied to the sealing portion. Accordingly, an adhesive force in the sealing region may be increased.
