A plurality of light-emitting units () are provided on a first surface () of a substrate () and are separated from each other. Each light-emitting unit () includes a light-transmitting first electrode (), an organic layer (), and a light-reflective second electrode (). The organic layer () is located between the first electrode () and the second electrode (). A light-transmitting region is located between the light-emitting units () and transmits light in the thickness direction of a light-emitting device (). An optical filter () overlaps the light-transmitting region and does not overlap the plurality of light-emitting units ().

Light-emitting device

A partition member () partitions a space occupied by a person from the outside. The space is, for example, an interior of a mobile object () such as a vehicle. A substrate () is disposed on a surface of the partition member () on the space side and has optical transparency. On a surface (a second surface ()) of the substrate () on the space side, a plurality of light-emitting units and an insulating layer () are disposed. Each light-emitting unit () includes a light-transmitting first electrode (), an organic layer (), and a second electrode () in this order from the external side. The insulating layer () defines the plurality of light-emitting units (). A third region (: a light-transmitting region) in the substrate () in which the second electrode () and the insulating layer () are not formed is provided between light-emitting units () next to each other.

It is an object of the present invention to inhibit a collapse of a color balance possibly caused due to deterioration of self-emission elements when performing a color displaying by virtue of several different colors. A self-emission display apparatus comprises: a display element section consisting of self-emission elements; a monitor element section consisting of self-emission elements of different colors formed in the same manner as the self-emission elements of the display element section; a power supply circuit which supplies driving voltages to the display element section; monitor detecting units for detecting an operating state of the monitor element section; driving voltage control units which control driving voltages in accordance with a detected operating state; and a display control section for supplying display signal to the display element section. Further, the self-emission display apparatus has monitor control units which perform lighting controls of the foregoing different colors on the monitor element section, as well as a monitor load adjusting unit which adjusts a load state of each of the foregoing different colors in lighting control so as to maintain a color balance of the display element section.

An organic electroluminescent display device includes organic electroluminescent films, each containing organic electroluminescent materials and sandwiched by a pair of electrodes, each forming a plurality of light-emitting elements above a substrate. Each pixel of the display device is composed of two different colors light-emitting elements, and the chromaticity of each color is controlled by changing the concentration of organic electroluminescent materials or by adding foreign materials thereto. For example, if the chromaticity of the red light-emitting element is set to a value shifted toward green side, various colors including white can be produced by mixing this red with blue of the blue light-emitting element. Then, the organic electroluminescent display device can produce high-quality quasi-color images by mixing two colors of which chromaticity values are properly controlled. By virtue of a two-color structure, the aperture ratio becomes high and the manufacturing process becomes simple.

There is provided an organic EL display device comprising: an underlying layer, including at least one layer formed of organic materials, formed on a substrate; organic EL elements formed thereon; and each leading electrode from the organic EL element for an electrical interconnection to an electrode of an interconnection object. In the display device, each connecting region is formed by removing the layers formed of organic materials, of the underlying layer, at a location of a thermocompression bonding for the electrical interconnection. This enables a reliable electrical interconnection between the leading electrode and the electrode of the interconnection object, thereby allowing a good display performance of each organic EL element to be kept.
