摘要： A light emitting device having a structure in which oxygen and moisture are prevented from reaching light emitting elements, and a method of manufacturing the same, are provided. Further, the light emitting elements are sealed by using a small number of process steps, without enclosing a drying agent. The present invention has a top surface emission structure. A substrate on which the light emitting elements are formed is bonded to a transparent sealing substrate. The structure is one in which a transparent second sealing material covers the entire surface of a pixel region when bonding the two substrates, and a first sealing material (having a higher viscosity than the second sealing material), which contains a gap material (filler, fine particles, or the like) for protecting a gap between the two substrates, surrounds the pixel region. The two substrates are sealed by the first sealing material and the second sealing material. Further, reaction between electrodes of the light emitting elements (cathodes or anodes) and the sealing materials can be prevented by covering the electrodes with a transparent protective layer for example, CaF2, MgF2, or BaF2.

摘要： There is disclosed a lightweight and small liquid crystal display which achieves low power consumption and in which the optical anisotropy of the liquid crystal material is compensated for in order to enhance the viewing angle characteristics and the response speed of the liquid crystal material. Display electrodes and a common electrode are formed on one of the substrates. The orientation of the liquid crystal material is of the HAN (hybrid alignment nematic) type. This compensates for the optical anisotropy of the liquid crystal material and improves the response speed.

摘要： 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.
