A deep UV LED chip includes a light-emitting unit, an electrode unit, an electron blocking layer, and an optical layer. The electron blocking layer is disposed between a multiple quantum well layer and a p-type aluminum gallium nitride layer of the light-emitting unit. The optical layer is formed on the light-emitting unit and has a refractive index ranging from 1.0 to 2.3. Another deep UV LED chip further includes a light-transmitting substrate. The optical layer is formed on the light-transmitting substrate and has a refractive index ranging from 1.0 to a refractive index of the light-transmitting substrate. A package structure containing the deep UV LED chip is also disclosed.
