Abstract: A panel support structure for supporting a flat display panel capable of reducing the weight of the panel support structure while a sufficient structural strength is maintained and capable of preventing the display performance of the flat display panel from being lowered by a change in an ambient temperature. A flat display panel is fixedly supported by an X-character shaped supporting member via dampers fitted in the four corners of the flat display panel by the flat panel fixing parts of the supporting member. The supporting member is disposed along diagonal lines extending between the four corners of the flat display panel and has a rectangular cross section whose longer side is directed in the thickness direction of the flat display panel.
