    • A light emitting device in accordance with the present invention includes a light emitting element and a light sensor for detecting the luminous intensity of the light emitted from the light emitting element. The light emitting element includes a lower electrode, a light emitting material layer including at least a light emitting layer, and an upper electrode having light transparency, which are formed on a substrate in the named order. One of the lower electrode and the upper electrode acts as a cathode, and the other acts as an anode. The light sensor is formed on the light emitting element. Thus, it is possible to provide the light emitting device so configured to sufficiently prevent the unevenness of luminance and the deterioration in color balance, and to efficiently guide the light emitted from the light emitting element to the light sensor, so as to enable to detect the luminous intensity of the emitted light with high sensitiveness, with a minimized adverse mutual influence between the light emitting element and the light sensor.
    • 根据本发明的发光器件包括发光元件和用于检测从发光元件发射的光的发光强度的光传感器。 发光元件包括下电极,至少包括发光层的发光材料层和具有透光性的上电极,其以所述顺序形成在基板上。 下电极和上电极中的一个用作阴极,另一个用作阳极。 光传感器形成在发光元件上。 因此,可以提供如此构造的发光器件,以充分防止亮度的不均匀性和色平衡的劣化,并且有效地将从发光元件发射的光引导到光传感器,以便能够检测 具有高灵敏度的发射光的发光强度,发光元件和光传感器之间的不利相互影响最小化。
