Abstract: The present invention provides an organic electroluminescence device capable of having not only a device lifetime comparable to that of an existing organic electroluminescence device but also a small thickness of smaller than 10 ?m and excellent flexibility. The present invention relates to an organic electroluminescence device having a structure including: an anode; a cathode on a substrate; and a laminate of multiple layers between the anode and the cathode, the device having a thickness of smaller than 10 ?m.

Abstract: To provide a display apparatus that makes it possible to further improve a performance in controlling video presentation according to characteristics of an eyeball of a user. A display apparatus is provided that includes a light source; a processor that performs processing on a distribution of characteristics of an eyeball; a monitoring section that monitors a state of the eyeball; a matching section that performs matching on the distribution of the characteristics of the eyeball and the state of the eyeball; and an irradiator that irradiates a specified position on a retina with video display light emitted by the light source.
