摘要:
A red color filter layer is provided under an organic EL device. A green color filter layer, a blue color filter layer, and a region without a color filter layer are provided in this order under an organic EL device. Orange light from the organic EL device is transmitted through the red color filter layer, so that red color is obtained. White light from the organic EL device is transmitted through the green color filter layer and the blue color filter layer, so that green light and blue light are obtained. White light is obtained from the organic EL device. In this way, red light, green light, blue light, and white light are obtained.
摘要:
An organic EL device has a structure that includes a hole injecting electrode, hole injecting layer, hole transporting layer, light emitting layer, electron restricting layer, electron transporting layer, and electron injecting electrode, in sequence, on a substrate. For the electron restricting layer, a material having an electron mobility lower than that of the electron transporting layer or a material having a low LUMO (lowest unoccupied molecular orbital) energy level is used.

A negative electrode for a nonaqueous electrolyte secondary battery and a nonaqueous electrolyte secondary battery including the negative electrode. The negative electrode is made from aluminum powder or aluminum alloy powder coated with carbon and a conductive polymer. Since aluminum or aluminum alloy has a theoretical maximum capacity as high as 1200 mAh/g, a battery having aluminum or aluminum alloy as the negative electrode material has a high capacity.
