摘要： In an organic electroluminescence element, a stray light which is confined in the inside of a light emitting layer, an anode and a glass substrate receives the conversion of angle at an end portion of a pixel restricting portion and is eradiated and hence, a substantial light emitting region is expanded from an original light emitting region. When such an organic electroluminescence element is used in an exposure device, the resolution is substantially lowered. To overcome such a drawback, the present invention provides an organic electroluminescence element includes an anode to which holes are injected, a light emitting layer, a cathode to which electrons are injected, and a pixel restricting portion which restricts a light emitting region of the light emitting layer by controlling the injection of at least one of the holes and the electrons, wherein a thickness of an end portion of the pixel restricting portion on a side thereof which restricts the light emitting region is set to a value equal to or more than 20 nm and equal to or less than 100 nm.

摘要： An image forming apparatus includes a light source provided with a converting means for converting the advancing direction of light emitted from the light source, whereby the direction in which the light source is disposed can be determined regardless of a direction in which light is emitted. The advancing direction of the light emitted from a light emitting element is converted into a direction in which the light transmitting means can transmit the light, so that the luminous intensity on the photosensitive drum can be increased. It is designed so as to increase a light emitting area of the light emitting element and condense the light emitted therefrom, in result the luminous flux density can be improved. The light emitting element applies a flat luminous unit, which is combined with a light transmitting means in one optical piece.

摘要： With a conventional organic light emitting element, the pixel formation accuracy is controlled by the pattern formation accuracy of an electrode provided on the top surface of an organic layer. Since this electrode pattern must be formed after an organic layer is formed, only the vapor deposition method with low pattern formation accuracy is available. It makes it difficult to form homogenous and fine pixels. In a production method of an organic light emitting element in this invention, after forming a first electrode composed of a transparent electrode and a metal layer, an organic layer coats the transparent electrodes exposed by removing those portions of a metal layer corresponding to pixels, a second electrode is formed on the organic layer. In this method, the pixel formation accuracy depends on only a metal layer removing accuracy. Since the metal layer is removed before the organic layer is formed, the photolithographic technique can be applied to enable homogeneous and fine pixels to be formed.
摘要翻译：利用传统的有机发光元件，通过设置在有机层的顶表面上的电极的图案形成精度来控制像素形成精度。由于该电极图案必须在形成有机层之后形成，所以仅具有低图案形成精度的气相沉积方法。这使得难以形成均匀和精细的像素。在本发明的有机发光元件的制造方法中，在形成由透明电极和金属层构成的第一电极之后，通过除去与像素对应的金属层的那些部分，有机层涂布曝光的透明电极，第二电极形成在有机层上。在该方法中，像素形成精度仅取决于金属层去除精度。由于在形成有机层之前去除了金属层，所以可以应用光刻技术来形成均匀和精细的像素。
