Semiconductor Light Emitting Device

By doping an organic compound functioning as an electron donor (hereinafter referred to as donor molecules) into an organic compound layer contacting a cathode, donor levels can be formed between respective LUMO (lowest unoccupied molecular orbital) levels between the cathode and the organic compound layer, and therefore electrons can be injected from the cathode, and transmission of the injected electrons can be performed with good efficiency. Further, there are no problems such as excessive energy loss, deterioration of the organic compound layer itself, and the like accompanying electron movement, and therefore an increase in the electron injecting characteristics and a decrease in the driver voltage can both be achieved without depending on the work function of the cathode material.

Light Emitting Device

A semiconductor light-emitting device and a method for manufacturing the same can include a wavelength converting layer encapsulating at least one semiconductor light-emitting chip to emit various colored lights including white light. The semiconductor light-emitting device can include a base board with the chip mounted thereon, a frame located on the base board, a transparent plate located on the wavelength converting layer, a reflective material layer disposed between the frame and both side surfaces of the wavelength converting layer and the transparent plate, and a light-absorbing layer located on the reflective material layer. The semiconductor light-emitting device can be configured to improve light-emitting efficiency and a contrast between a light-emitting and non-light-emitting surfaces by using the transparent material and light-absorbing layer. A wavelength-converted light that is emitted can have a high light-emitting efficiency and a high contrast between a light-emitting and non-light-emitting surface from a small light-emitting surface.
