According to the above configuration, heat generated in the display body and the control circuit portion is easily transmitted to the cabinet, and heat radiation is promoted. Further, the thermoelectric converter generates power in the process of transmitting the heat of the display to the cabinet. By storing this in a charging circuit, it can be used as driving power for various circuits. That is, energy can be saved.

It becomes the hottest due to the heat transfer from the thermoelectric converter to the cabinet and the convection due to the rise of the heated air. However, with the configuration in which the heat radiation fins are provided, heat can be efficiently radiated, and the conventional heat radiation holes can be eliminated.

The above-mentioned cabinet is not limited to the two-segment type structure composed of the first and second cabinets, but it goes without saying that the two cabinets may be integrated into one cabinet. In addition, the thermoelectric conversion device is not limited to the connection between the CRT and the first cabinet, but may be a connection medium between the CRT and the second cabinet.

When it is difficult to interpose a thermoelectric converter between the CRT and the cabinet, the thermoelectric converter may be mounted only on the cabinet side. In that case, the mounting location is arbitrary, the inner surface of the cabinet,
The outer side does not matter.

Further, the thermoelectric converters may be arranged at four places on the top surface (upper surface), both side surfaces, and the bottom surface (lower surface) of the display body, and each may be contacted (connected) to the cabinet so as to be able to conduct heat.

The heat transfer member 55 was formed in a substantially oval pipe shape having a hollow portion by a composite body of graphite and fluororesin. By providing a hollow portion at the center, even if the distance between the CRT and the first cabinet 52 varies, the heat transfer member 55 can be absorbed by elastic deformation.

That is, the display body and the cabinet are connected so as to be able to conduct heat by a thermoelectric converter, and the thermoelectric converter and the cabinet mounted on the printed circuit board of the control circuit are also connected so as to be able to conduct heat.

With this configuration, heat is transferred from both the display body and the control circuit block to the cabinet, and heat radiation and power generation are promoted.

In this case as well, it goes without saying that the heat absorbing side of the thermoelectric converter may be connected to an arbitrary portion such as the top surface, both side surfaces, the low surface, and the back surface of the display body. The mounting location of the thermoelectric conversion device mounted on the printed wiring board may be arbitrarily set.

(Embodiment 4) The television receiver in this case has basically the same configuration as that of Embodiment 1.

With this configuration, heat is transferred from both the display body and the control circuit block to the cabinet, and heat dissipation is promoted.

In this case, it goes without saying that the heat transfer member may be connected to an arbitrary portion such as the top surface, both side surfaces, the low surface, and the back surface of the display body. The attachment location of the heat transfer member connected to the printed wiring board may be arbitrarily set.
