| abstract |
The present invention can be adopted in the inkjet printing method, and a non-polar or weak polar material can be used as a functional material, to prevent clogging during discharge, to achieve stable discharge, and to precipitate contents and to form a film during discharge. A composition for preventing phase separation, a uniform and homogeneous functional film formed using the same, a method for manufacturing the same, a display device such as an organic EL device, and a method for manufacturing the same. The composition of this invention consists of a solvent and a functional material which have at least 1 type of benzene derivative which has one or more substituents, and the total carbon number of this substituent is 3 or more. The functional film of this invention is formed using the said composition. The display device of the present invention includes a light emitting material layer formed by using the composition between two electrodes. The display device is an organic EL element or the like. |
