A display device is provided having enhanced precision and accuracy in attachment of a plasma display panel to a chassis base. A method and apparatus for manufacturing such a display device is also provided. The display device may include a display panel having an upper panel and a lower panel and a chassis base for supporting the display panel. At least one panel of upper and lower panels in a plasma display panel is marked with an aligning mark, and a penetration hole is formed at a chassis base at a position corresponding to the aligning mark. Therefore, the chassis base and the plasma display panel may be precisely aligned on the basis of the aligning mark exposed through the penetration hole.
