Display unit and mobile apparatus using the unit

A display unit comprising:

• a display device having a display screen;
• a secondary battery disposed to a rear side of said display device;
• and
• a heat shielding layer interposed between said display device and the secondary battery, said heat shielding layer having a thermal conductivity of at most 5 W/mK;
• and
• a heat radiating layer or a cooling layer disposed to said secondary battery at a side opposing to a side of said display device;
• wherein said display device and the secondary battery are integrally assembled to form a module structure.
