A method for transferring a micro device on a curved surface according to an exemplary embodiment of the present invention includes: coating an adhesive layer on an external circumferential surface of a tube; providing a micro device pattern on one side of a substrate; positioning an external circumferential surface of the tube to contact the substrate and allow a length direction of the device pattern to cross a radius direction of the tube, and rotating the tube with respect to an axis-direction of the tube and simultaneously moving at least one of the tube and the substrate in a rectilinear way to transfer the micro device pattern on the substrate to the adhesive layer; and fixing the transferred micro device pattern to the adhesive layer by curing the adhesive layer.

Method for transferring micro device on curved surface and apparatus for transferring micro device on curved surface

An exemplary embodiment of the present invention provides a method of transferring a micro device. The method of transferring the micro device includes: separating a transferring film from a micro device transferred to a target substrate and bending the transferring film upwardly to form a bent circular arc, and pressurizing an upper transferring film fed after the bent circular arc is formed by a pressurizing roller rotating at an upper side of the target substrate.

Method and apparatus for transferring micro device, and electronic product using the same

The present invention provides a retardation film that comprises a) a first acrylic resin layer; and b) a second acrylic resin layer that is layered on at least one side of a) the first acrylic resin layer and comprises an acrylic resin and 1 to 20 parts by weight of rubber component based on 100 parts by weight of the acrylic resin. The retardation film according to the present invention has excellent optical transparency, haze, brittleness, mechanical strength, heat resistance, durability, and the like.

Multi-layered acrylic retardation film and fabrication method thereof

Disclosed is an optical film that is manufactured by using longitudinal and uniaxial stretching of an unstretched cycloolefin copolymer film and has an in-plane retardation of 100 to 150 nm and a thickness retardation of 0 to &#x2212;30 nm at a wavelength of 550 nm, a polarizing plate and a liquid crystal display including the same, and a method of manufacturing the optical film. The method includes longitudinally and uniaxially stretching the unstretched film while a ratio of a width to a length of a stretched portion of the film is controlled.
