Patent ID: 8284328

Claim:
A display apparatus comprising: a display module generating heat; a substrate having a mounting surface and being placed at an interval from said display module; a component group mounted on said mounting surface; a housing storing said display module, said substrate, and said component group, wherein (i) said mounting surface includes a first surface extending opposite to said display module and a second surface placed at a rear side of said first surface, (ii) a component in said component group having the greatest height with respect to said mounting surface is mounted on said first surface selected from said first surface and said second surface, (iii) said housing is provided with a first air vent hole positioned below said substrate and a second air vent hole positioned above said substrate, and (iv) an airflow circulating through said first air vent hole, space between said display module and said first surface, and said second air vent hole is created within said housing, and and additional substrate stored in said housing and provided separately from said substrate, said additional substrate being placed in a path of airflow from said first air vent hole to the space between said display module and said first surface, and positioned such that an interval between said display module and said additional substrate is smaller than an interval between said first air vent hole and said additional substrate.
