2. Description of the Related Art A PDP for displaying television images and the like is an excellent display device which is thin and capable of displaying a large screen. However, since it is thin and self-luminous, it is necessary to have a structure capable of sufficiently radiating heat. . However, due to the nature of the display device, the front of the PDP must be open, and
Since it is necessary to provide a drive circuit board or the like closely on the back surface in order to take advantage of the thin characteristics, sufficient heat dissipation becomes difficult. Therefore, a method of removing heat from a narrow space by using a heat pipe can be considered, but there is no satisfactory mounting structure in terms of heat dissipation efficiency.
