1. A display apparatus comprising:
a display panel for displaying an image;
a heat source arranged at a side surface of at least one side of the display panel, the heat source emits visible light;
a heat absorbing section for absorbing heat generated by the heat source;
a back surface plate comprising a metal arranged at a back surface side of the display panel, wherein a portion of the back surface plate is in close contact with the heat absorbing section;
an optical waveguide arranged at the back surface side of the display panel;
a front surface plate arranged at a front surface side of the display panel;
a middle chassis arranged between the front surface plate and the heat absorbing section;
a back chassis arranged at a back surface side of the back surface plate; and
a panel control board mounted on the back chassis, the panel control board controlling drive of the display panel and being located at a central portion of the back surface side of the back surface plate, and
wherein when the generated heat is absorbed by the heat absorbing section, an amount of heat discharged from the front surface plate is less than that discharged from the back surface plate,
wherein the front surface plate has a peripheral portion that extend rearward to overlap the back surface plate, the peripheral portion being devoid of apertures, and
wherein the peripheral portion of the front surface plate has a tapered portion extending from a front surface side of the front surface plate to a back surface side of the front surface plate so as to make the back surface side of the front surface plate smaller.
