摘要： More efficient radiation of heat from a point-like light source is enabled, and thinning is promoted, while higher and more uniform brightness of a planar illumination device is accommodated. A radiation path is formed through which the heat generated from the point-like light source is transmitted to a radiator plate made of metal through an electrode terminal of the point-like light source, a land portion of a front side face of an FPC, a through hole of a conductor pattern, and a high heat-conductive resin. The radiation path for efficient radiation from a conductor pattern of the FPC to the radiator plate made of metal is extended, and direct radiation area is sufficiently ensured. Particularly even if a large-current type LED is used for the point-like light source, sufficient radiation effect can be obtained. Also, since freedom in wiring pattern on the FPC and freedom of outline are not different from a conventional FPC at all, a demand for thinning of the planar illumination device can be sufficiently satisfied.

摘要： A field-effect transistor has a source region, a drain region, a gate electrode, and a low resistivity layer. The source and drain regions are of a first conductivity type and formed as surface regions of a semiconductor layer formed on one of an insulating substrate and a semi-insulating substrate. The gate electrode is formed on a channel region between the source region and the drain region. The low resistivity layer serving as a shield layer is disposed underneath and spaced apart from the source, drain and channel regions, and overlaps the source region with an overlap area being larger than an overlap area between the low resistivity layer and the drain region. The arrangement enables the prevention of noise margin reduction and erroneous operation.
