ROLLER DEVICE USING SUCTION ROLLER, PRODUCTION METHOD FOR MEMBER HAVING UNEVEN STRUCTURE AND PRODUCTION METHOD FOR ORGANIC EL ELEMENT

摘要

A roller device (300) provided with: a rotatable suction roller (25), wherein a suction force acts at the outer peripheral surface (25a) from the outside towards the inside; a suction mechanism (65) which generates the suction force; and a gas permeable member (81) which covers the outer peripheral surface (25a) of the suction roller (25). Due to the roller device (300) being provided with the gas permeable member (81) and the suction roller (25), water gas can be uniformly extracted from a workpiece while the workpiece is impelled by the gas permeable member (81). By using this roller device (300), a member having an uneven structure to be used for light diffraction and scattering can be produced at a good yield and a high throughput.
