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.
