Abstract: A heat sink 41 is provided on a lower edge side, for example, of a display panel 21 with a heat radiation surface being on a display surface side of the display panel 21. A heat source, such as a light source 22, which generates heat owing to display operation using the display panel 21 is mounted on a mounting face opposite to the heat radiation surface. A cover 31 that covers the heat sink 41 is provided on the display surface side of the display panel 21. Air holes 311 and 312 are formed on a top face 31t and a bottom face 31b, respectively, of the cover 31. Air taken in through the air holes 312 on the bottom face 31b of the cover 31 cools the heat sink 41, and the air heated by the heat of the heat sink 41 is dissipated outside through the air holes 311 on the top face 31t. Heat generated inside the display device is efficiently dissipated with a small ventilation resistance without generation of noise. Since heat is dissipated on the display surface side, discoloration of wall paper on a mounting face and the like is prevented or reduced.

Abstract: An image processing unit includes: a gain calculating section obtaining, based on first luminance information for each pixel, a first gain, in which the first gain is configured to increase with an increase in pixel luminance value in a range where the pixel luminance value is equal to or larger than a predetermined luminance value, and in which the pixel luminance value is derived from the first luminance information; and a determination section determining, based on the first luminance information and the first gain, second luminance information for each of the pixels.
