摘要:
A blue organic EL device with an improved EL luminescence efficiency where an energy barrier is reduced during injection of holes or electrons from an anode or cathode to facilitate charge injection; a charge transporting layer acts as a blocking layer preventing holes or electrons from passing through a luminescent layer; and a recombination of holes and electrons is effectively performed. An organic electroluminescent device have at least two organic-compound layers selected from the group consisting of a luminescent layer emitting a blue light, an electron injection layer and an electron transporting layer between heteropolar electrodes, wherein the electron injection or electron transporting layer has an ionization potential higher than that of the luminescent layer.

A super thin film is composed of an organic compound having a sulfur-atom-containing substituent in a specific structure, such as mercapto, sulfide and disulfide groups. Among them, the most preferred one is an alkyl mercapto group represented by —(CH2)nSH in which n is an integer of 1-10. The super thin film is then introduced into the interface between at least one electrode and an organic layer being in contact therewith for receiving carriers from the electrode and delivering the carriers to the organic layer to provide organic EL devices and EL panels. The compound also has a molecular structure similar to that of an organic material at forms the organic layer. The compound can suppress the generation of dark spots and the increase of power consumption. Therefore, it is possible to manufacture organic EL devices with an excellent durability and a smaller increase in power consumption and also panels using the devices.

A hermetic encapsulation package and a method of fabricating such package, wherein at least one organic electroluminescent (EL) element is formed on a support substrate. A sealing cap for accommodating the organic EL element is bonded to the support substrate with an ultraviolet curing resin to form a sealed space defined by the sealing cap and the support substrate. At least part of the sealing cap is formed of an elastic material of a Young's modulus of 70 GPa or less. The elastic portion of the sealing cap is reversibly deflected to provide a decrease or increase in the volume of the sealed space to reduce pressure changes inside the sealed space caused by changes in temperature, thereby alleviating problems of thermal shock.

A color filter having two-layered light-shielding sections without a black matrix is provided, which reduces the level difference from the colored materials for pixels with a simple method and makes it possible to remove the color layer on the said sections. A red color layer having stripe-shaped red pixel formation sections and a blue color layer having stripe-shaped blue pixel formation sections are overlapped to form two-layered light-shielding sections. A green color layer having island-shaped green pixel formation sections is overlapped with the red and blue color layers, placing the green pixel formation sections in the overlapped green pixel windows of the red and blue color layers. Only the peripheries of the green pixel formation sections are placed on the light-shielding sections to facilitate the removal of the peripheries by polishing.
