An integrated circuit package includes a die mounted on a substrate, an integrated heat spreader set above the die, and an array of carbon nanotubes mounted between the die and the integrated heat spreader. The integrated heat spreader is fixed on the substrate, and includes an inner face. The array of carbon nanotubes is formed on the inner face of the integrated heat spreader. Top and bottom ends of the carbon nanotubes perpendicularly contact the integrated heat spreader and the die respectively. Each carbon nanotube can be capsulated in a nanometer-scale metal having a high heat conduction coefficient.

A planar light source device () for a display device includes a light guide plate () and pluralities of light emitting diodes (). The light guide plate has a light incident surface (). The light emitting diodes are located in the vicinity of the light incident surface. Each light emitting diode has a light emission surface opposite to the light incident surface of the light guide plate, and has a diffraction grating () provided on the light emission surface for improving a range of divergence of light beams emitted therefrom.
