A flat panel display apparatus includes a panel including an image region on which an image is realized, a window covering the panel, a black matrix formed in the window along a side edge of the image region, and a resin layer that is ultraviolet (UV) curable and that bonds the panel and the window. The black matrix includes a black ink part for blocking UV rays, and a diffusion ink part for transmitting UV rays. In the flat panel display apparatus, the resin layer for window bonding is sufficiently cured in all regions, including a region thereof under the black matrix, so that a bonding defect in the window due to insufficient curing of the resin layer is significantly decreased.
