The present specification relates to an ink composition including a first solvent represented by Chemical Formula 1 and a compound represented by Chemical Formula 2; an ink composition including a first solvent represented by Chemical Formula 1, a second solvent represented by Chemical Formula 3 or Chemical Formula 4, and a compound represented by Chemical Formula 2; an organic light emitting device including the ink composition and a cured material thereof; and a method for manufacturing the same.

Ink composition, organic light-emitting device using same, and manufacturing method therefor

The present invention relates to an ink composition for an organic light emitting device that can be applied to an inkjet process. The ink composition comprises a compound represented by the following Chemical Formula 1, a first solvent of aromatic esters having a boiling point of 260 to 400&#xb0; C., and a second solvent of aliphatic ethers or aliphatic esters having a boiling point of 200 to 400&#xb0; C., wherein the boiling point of the first solvent is higher than that of the second solvent. When this is applied to an inkjet process, it can form a flat film with a smooth surface when dried after forming the ink film. wherein L, Lto L, Ar, Ar, Rto R, Yto Y, and nto nare described herein.

Ink composition for organic light emitting device

The present specification relates to an ink composition comprising a solvent comprising a solvent represented by Chemical Formula 1, a solvent represented by Chemical Formula 2 and a solvent represented by Chemical Formula 3; and a charge transferring material or a light emitting material, and a method for manufacturing an organic light emitting device formed using the ink composition.

Ink composition and method for manufacturing organic light emitting device

The present specification relates to an ink composition including: a compound represented by Formula 1; and a solvent represented by the Formula 2, and a method for manufacturing an organic light emitting device formed by using the ink composition.

The present invention relates to an ink composition for an organic light emitting device that can be applied to an inkjet process. When the inkjet process is applied using this, it is possible to form a film having smooth and flat surfaces when dried after forming an ink film.

The present specification relates to an ink composition comprising a solvent comprising one or more types of Chemical Formulae 1 to 4; and a charge transferring material or a light emitting material, an organic light emitting device using the same, and a method for manufacturing the same.

Ink composition, organic light-emitting element using same, and fabrication method thereof

Provided are a single-sided one-sheet type capacitive touch screen and a method for manufacturing the same. The touch screen includes: a substrate; a first conductive pattern disposed on the substrate in a vertical direction and including at least two pattern columns having two or more conductive pattern regions electrically connected with each other; a second conductive pattern disposed on the same surface of the substrate as the surface where the first conductive pattern is disposed, not being electrically connected with the first conductive pattern, and including two or more conductive pattern regions not electrically connected with each other; a transparent conductive bridge electrically connecting the conductive pattern regions of the second conductive pattern in a horizontal direction; and a transparent insulating part disposed between the transparent conductive bridge and the first conductive pattern to electrically insulate the transparent conductive bridge and the first conductive pattern.

Touch screen and method for manufacturing the same

A heat-curable ink composition and a color filter produced using the ink composition are provided. The ink composition and the color filter are highly resistant to heat and chemicals due to the use of a polyester resin prepared by polycondensation. In addition, unreacted anhydride groups are removed using a monohydric alcohol in the preparation of the ink composition to make the ink composition and the color filter very stable during storage.
