明装置付表示装置。 In a display device with an internal illumination device configured to use fluorescent tubes as an internal illumination device of the display device, the fluorescent tubes are provided at regular intervals, and the temperature is below a temperature condition that does not require heat radiation. At the time, the above-mentioned distance is maintained with the fluorescent tube, and when the fluorescent tube is above the temperature condition that requires heat radiation, the shape is such that it can come into contact with the fluorescent tube and radiate the heat to the heat radiating section. In order to deform the fluorescent tube so that the shape becomes A temperature switch is provided in which a constant elastic material is bonded to the shape memory alloy on the side opposite to the fluorescent tube in order to maintain a constant distance from the fluorescent tube when the temperature does not require heat dissipation. A display device with an internal lighting device characterized by:
