  • Patent number: 9093668
    Abstract: A display apparatus includes a sealing portion. A method for fabricating the sealing portion includes: irradiating a pulse laser beam onto a deposition target to form the sealing portion at an edge where a substrate and an encapsulation face each, wherein a display unit is formed on the substrate, and the encapsulation is configured to seal the substrate; bonding the substrate and the encapsulation to each other; hardening the sealing portion; and monitoring the sealing portion. Thus, structural strength of the sealing portion is improved.
