ELECTRIC FIELD LIGHT EMITTING ELEMENT |
摘要 |
An organic EL element that is an electroluminescence element has at least an organic layer held between a pair of electrodes. At least an electrode made of material having a higher volume resistivity, of the pair of electrodes, is formed in a flat form. The organic layer is provided with a plurality of non-light emitting portions. The non-light emitting portions are provided so that a larger number of non-light emitting portions exist per unit area at a position physically closer to the position of a terminal portion at which the electrode made of material having the higher volume resistivity is connected to an external connection terminal. As a result, the level of current passing per unit area is substantially uniform at each position on the element.
