Abstract: A method of manufacturing a roll type imprint master mold including disposing a base layer on a substrate including a first area and a second area adjacent to the first area, disposing an inorganic insulation layer on the base layer, forming a first mask pattern and a first resin pattern in the first area, forming a pattern layer by etching the inorganic insulation layer using the first resin and the first mask patterns as a mask, removing the first resin and the first mask patterns, forming a second mask pattern and a second resin pattern in the second area, forming a pattern layer by etching the inorganic insulation layer using the second resin and the second mask patterns as a mask, removing the second resin and the second mask patterns, separating the base layer from the substrate, and attaching the base layer onto a roll body.

Abstract: A display device may include a first transistor, a first electrode, a second electrode, a first intermediate layer, and a first changeable layer. The first electrode is electrically connected to the first transistor. The second electrode overlaps the first electrode. The first intermediate layer is positioned between the first electrode and the second electrode and may emit first light when the first electrode and the second electrode generate a first electric field. The first changeable layer, which overlaps the first electrode, may have a first transmittance value when the first electrode and the second electrode generate the first electric field, and may have a second transmittance value when the first electrode and the second electrode do not generate the first electric field. The second transmittance value is unequal to the first transmittance value.

Abstract: The present invention relates to a method of separating fine particles by measuring the magnetic susceptibilities thereof using isomagnetophoresis. In a system for separating fine particles using isomagnetophoresis according to the present invention, fluids having different magnetic susceptibilities and fine particles to be measured are introduced into a microfluidic channel to form a magnetic susceptibility gradient, a strong magnetic field is applied to the channel to control the behavior of the introduced fine particles, thus moving the fine particles to respective positions at which the fluids having magnetic susceptibilities identical to those thereof is present. According to the present invention, fine particles having a fine difference in magnetic susceptibility can be separated from each other by measuring the magnetic susceptibilities thereof.
