Title: COMPOSITE MATERIAL, LIGHT-EMITTINTG ELEMENT, LIGHT-EMITTING DEVICE, AND MANUFACTURING METHOD THEREOF
Abstract:
It is an object of the present invention to provide a composite material that can be used for manufacturing a heat-resistant light-emitting element, provide a composite material that can be used for manufacturing a heat-resistant light-emitting element that can be driven with stability for a long period of time, and further, provide a composite material that can be used for manufacturing a light-emitting element that easily prevents short circuit between electrodes and uses less power. The present invention provides a composite material that has a first metal oxide skeleton including a first metal atom and an organic compound that is bound to the first metal atom by forming a chelate, where the first metal oxide exhibits an electron accepting property to the organic compound.
