Abstract
A radiating member, an illuminating device, an electro-optical device, and an electronic device are provided which are capable of absorbing the heat generated from an LED, thereby increasing the amount of electric current flowable through the LED. More particularly, there are provided a point light source, a light guide plate for receiving the light radiated from the point light source, and a radiating plate including an adhesive layer formed to contact the point light source, and a metal layer formed over the adhesive layer and made of the material having a thermal conductivity (λ) equal to or greater than 90 W/mK at room temperature.
