摘要:
Provided are a semiconductor package and a plasma display device including the same. The semiconductor package includes a film substrate that relays a signal between a circuit board and a display panel; a semiconductor chip that is electrically connected to the film substrate; a reinforcement plate to which the film substrate and the semiconductor chip are connected to via adhesive layers, and that provides a floating ground; and a connecting member that electrically connects the reinforcement plate and a ground of the semiconductor chip, and that electrically connects the reinforcement plate and a ground of the film substrate. Accordingly, the semiconductor package has excellent heat dissipation performance and ground stability.
