摘要： To provide a display device with higher image quality and reliability or a large-sized display device with a large screen at low cost with high productivity. A function layer (such as a coloring layer or a pixel electrode layer) used in the display device is formed by discharging a liquid function-layer-forming material to an opening formed with a layer including a first organic compound which has a C—N bond or a C—O bond in the main chain as a base and a layer including a second organic compound as a partition. The fluorine density exhibiting liquid repellency to the liquid function-layer-forming material, which is attached to a surface of the layers including organic compounds, is controlled, whereby a liquid repellent region and a lyophilic region can be selectively formed.

摘要： A novel carbazole compound that can be used for a transport layer, a host material, or a light-emitting material in a light-emitting element. In the carbazole compound, two carbazole skeletons each include carbazole, the 3-position of which is bonded to the 4-position of a dibenzofuran skeleton or a dibenzothiophene skeleton and these two carbazole skeletons are linked via benzene or biphenyl. The carbazole compound has an excellent carrier-transport property and a wide energy gap and can be suitably used for a material in a light-emitting element or for an organic semiconductor material.
