<p>A light-emitting diode device includes a light-emitting diode chip, lead-frames respectively connected to an anode and a cathode of the light-emitting diode chip, an encapsulant for encapsulating the light-emitting diode chip and the lead-frames, and a buffer layer, formed between the encapsulant, on the one hand, and the light-emitting diode chip and the lead-frames, on the other, for reducing the stress acting from the encapsulant onto the light-emitting diode chip and the lead-frames. This device can be minimized degradation of quality caused by this stress, and maintained high product quality for a long period of time. An encapsulating epoxy resin composition contains 100 parts by weight of an epoxy resin, 70 to 140 parts by weight of a curing agent including an acid anhydride, 0.5 to 4.0 parts by weight of a curing accelerator including an onium or diazabicycloalkene salt, and 0.1 to 5.0 parts by weight of a thiophosphite. This resin composition can be suitably used as an encapsulant for LED devices.</p> |
