The present invention relates to a method for labelling fluorine-18, which is a radioisotope, and more specifically, to a method for labelling a [F]fluoride in a method for preparing an organic [F]fluoro compound by reacting an alkyl halide or an alkyl sulfonate with a [F]fluoride, wherein a [F]fluoride supported on a quaternary alkyl ammonium polymer support is eluted using a solution containing a metal salt or a quaternary ammonium salt with an adjusted pH, and a base is not additionally used. The present invention enables a labeling reaction without an additional base after precisely reflecting the concentration of a base absolutely necessary for the nucleophilic substitution of a [F]fluoride or eluting a [F]fluoride using a [F]fluoride eluent with an adjusted pH, thereby stably obtaining a [F]fluoride-labelled compound in a high yield, and is thus useful for production of fluorine-18-labelled radioactive medical supplies.

The present inventive concept relates to a display device and a manufacturing method thereof. A display device according to an exemplary embodiment of the present inventive concept includes: a substrate; a first gate conductor provided on the substrate; and a gate insulator provided on the first gate conductors, wherein edges of the first gate conductor are recessed from edges of the first gate insulator, and the edges of the first gate insulator are respectively parallel with the edges of the first gate conductor.

Display device and manufacturing method thereof

A display device is provided. The display device includes a base; a gate conductor disposed directly on the base and including a gate line and a gate electrode; a gate insulating layer disposed on the gate conductor and including an overlap portion, which overlaps with the gate conductor, and a non-overlap portion, which is connected to the overlap portion, does not overlap with the gate conductor, and is spaced apart from the base; and a semiconductor pattern disposed on the gate insulating layer and overlapping with the gate electrode, wherein edges of the gate insulating layer project further than edges of the gate conductor and edges of the semiconductor pattern.
