Abstract
A light device solvent, a light emitting device ink comprising same, and a method for manufacturing a display device are provided. A method for manufacturing a display device comprises the acts of: spraying a device ink, which comprises a first element solvent and a light emitting element dispersed in the first element solvent, onto a target substrate having a first electrode and a second electrode thereon; forming a second element solvent, which has an isomeric structure of the molecular structure of the first element solvent, and loading the light emitting element on the first electrode and the second electrode; and removing the second element solvent.
Claims20
A method for manufacturing a display device, the method comprising:

- forming a second element solvent having an isomeric structure of a molecular structure of the first element solvent, and loading the light emitting elements on the first electrode and the second electrode;
- and
- removing the second element solvent.
A light emitting element solvent in which light emitting elements comprising semiconductor crystals are dispersed, the light emitting element solvent comprising:
- a first functional group and a second functional group which are represented by Chemical Formula 1 below;
- and
- a third functional group which comprises at least one double bond having an isomeric structure and bonded to the first functional group and the second functional group and
- the light emitting element solvent comprises at least any one of compounds represented by Chemical Formulae 2 through 6:
- wherein n is an integer of 1 to 5, and R3 is any one of a C1-C5 alkyl group, a C2-C5 alkenyl group, a C2-C5 alkynyl group, a C1-C5 alkyl ether group, a C2-C5 alkenyl ether group, and a C2-C5 alkyl ester group,
- and
- wherein R1 and R2 are represented by Chemical Formula 1, and the sum of an n value (n1) of R1 and an n value (n2) of R2 represented by Chemical Formula 1 is in a range of 2 to 6.
