20090008128 | ELECTRONIC APPARATUS - The invention provides an electronic apparatus having a metal core substrate including a metal plate, an insulating layer formed on the metal plate and a conductive layer formed on the insulating layer, and an electronic part, and to which the conductive layer and a terminal of the electronic part are connected. In the electronic apparatus, a member having a high thermal conductivity is arranged so as to be in contact with both of the metal plate and the electronic part. Accordingly, a heat radiating property of the electronic apparatus is increased. | 01-08-2009 |
20100277450 | Display Device - A display device includes a first substrate having a display area with a plurality of pixels on a main surface and a first seal area formed at a periphery of the display area, and a second substrate disposed to cover the main surface of the first substrate, and having a second seal area at a part of the second substrate opposite to the first seal area. At least one driving circuit is arranged outside of the display area on the first substrate. The second substrate has a recessed portion formed at a part of the main surface of the second substrate within the second seal area, and a film coats the recessed portion and/or an outside of the second substrate. A moisture absorbent layer is arranged in the recessed portion so as to be adhered to the recessed portion or the film when the film coats the recessed portion. | 11-04-2010 |
