PATTERN TRANSFER METHOD AND APPARATUS, FLEXIBLE DISPLAY PANEL, FLEXIBLE SOLAR CELL, ELECTRONIC BOOK, THIN FILM TRANSISTOR, ELECTROMAGNETIC-SHIELDING SHEET, AND FLEXIBLE PRINTED CIRCUIT BOARD APPLYING THEREOF

摘要

The present invention relates to methods and apparatuses for transferring pattern, a flexible display panel, a flexible solar cell, an electronic book, a thin film transistor, an electromagnetic-shielding sheet, and a flexible printed circuit board applying thereof. A pattern transfer method related to the present invention comprises: a first step of forming a transfer material layer on a substrate; a second step of hardening the transfer material layer in the solid state; a third step of patterning the transfer material layer by irradiating a laser beam to the hardened transfer material layer in the solid state; and a fourth step of pressing the patterned transfer material layer in the solid state and a flexible substrate facing each other and transferring the transfer material layer to the flexible substrate by a viscous force of the flexible substrate occurring in a facing part between the transfer material layer and the flexible substrate by irradiating the laser beam from the transfer material layer to the flexible substrate or from the flexible substrate to the transfer material layer.
