LINEAR LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a linear light-emitting device having improved efficiency in implanting electrons and holes in a light-emitting layer by reducing a large Schottky barrier generated between an electrode and a semiconductor layer. SOLUTION: The linear light-emitting device is provided with a pair of first and second linear electrodes provided opposed with each other and a linear light-emitting layer provided between a pair of the electrodes. At least one of a pair of the first and second electrodes is a transparent electrode and at least a buffer layer is also provided between the first or second electrode and the light-emitting layer. Since the buffer layer is provided, the size of a potential barrier between the electrode holding the buffer layer and the light-emitting layer becomes smaller than the Schottky barrier in the case where the electrode is placed directly in contact with the light-emitting layer.
