摘要： An organic EL device having a light emitting element including a first electrode (2), a second electrode (4) of transparent conductive film, and a light emitting organic material layer (9) formed between said first electrode (2) and said second electrode (4), wherein said transparent conductive film is made of a metal oxide deficient in oxygen as compared with stoichiometric composition. Since the transparent conductive film (4) directly in contact with the light emitting organic material layer (9) over a wide area is made of the metal oxide deficient in oxygen as compared with stoichiometric composition, the transparent conductive film can absorb moisture and oxygen which may possibly absorbed by the light emitting organic material layer so that the light emitting organic material layer is prevented from deteriorating, and the long emission lifetime of the element can be ensured.

摘要： An organic light-emitting device is provided, which increases the proportion of available light as much as possible and which produces higher brightness with less input power. The light-emitting device comprises: (a) a base having a surface; (b) a first electrode and a second electrode formed on the surface of the base; the first and second electrodes being located to be opposite to each other; (c) a light-emitting material layer located between the first and second electrodes; the light-emitting material layer having a first part and a second part; the first part being inclined with respect to the surface of the base at an inclination angle within a range from 45° to 90°; the second part being approximately parallel to the surface of the base; and (d) a carrier-blocking layer formed between the first electrode and the second part of the light-emitting material layer; the carrier-blocking layer having a function of blocking carriers emitted from the first electrode into the light-emitting material layer. The first part of the light-emitting material layer forms as a light-emitting region while the second part of the light-omitting material layer forms a non-light-emitting region. The output light is emitted from the light-emitting material layer by way of the base or the second electrode.
