摘要： PROBLEM TO BE SOLVED: To solve problems that in a conventional light emitting element of resonator structure, because there is little degree of freedom of film thickness adjustment of electron transport layer in order to adjust electric charge balance of the light emitting element, adjustment of the phase of electromagnetic wave is scarcely possible when it is emitted from a light emitting layer and reflected by a metal electrode and arrives again to the light emitting layer, furthermore that the arriving excitation state at the metal electrode is deactivated to cause non-light emission because a material which has a long time of several μ seconds or more in excitation and relaxation time moves and is diffused for a long distance from the light emitting layer until the excitation state is dissipated, and that a high brightness or a high efficiency is not achieved in a conventional light emitting element of the resonator structure.
SOLUTION: By using a transparent conductive film in a hole transport layer 203, a light emitting layer 204, an electron transport layer 205, and both an anode 202A of organic light emitting element having an electron injection layer 206 and a cathode 202B, and by installing films 201, 207 having light reflecting function outside the anode 202A and the cathode 202B respectively, the organic light emitting element in which the two problems have been simultaneously solved. In the organic light emitting element, a high efficiency, prevention of efficiency reduction on the high brightness side, and resonator effect can be introduced.

摘要： PROBLEM TO BE SOLVED: To provide an organic light-emitting element solving such a problem as lowering of efficiency caused by an attenuation or extinction of light emitted from the end surface of a film.
SOLUTION: In the organic light-emitting element having a metal thin film formed on an upper part of an organic thin film, the metal thin film is mechanically cut, and the film of that shape, obtained as a result of the above cutting, is used as a mask. Further, for the whole part of the organic thin film and a part of the thin film formed above and below the organic thin film, the lateral end surface of the thin film is processed by dry etching. By the above, the end surface of the film is made to function as a translucent reflection mirror to reduce loss by making the light reenter into the film at a prescribed proportion, and total amount of effective light getting out from the front surface of the film is increased to improve an amount of output light per input energy.
