Laser patterning apparatus and laser patterning method

Abstract

Aspects of the invention are directed to laser patterning apparatus capable of performing laser patterning on a thin film formed on a flexible substrate with a good yield and a laser patterning method thereof. The thin film formed on the flexible substrate can be patterned by laser using a laser patterning apparatus that can include a processing stage that has a reference processing surface on which the flexible substrate having the thin film formed thereon is disposed, a wrinkle removing device that is configured as a mechanism for stretching an outer periphery of a processing region of the flexible substrate so that tension is applied outward in the width direction and forward and backward in the transporting direction, and a laser scanner that scans a predetermined line of the thin film formed on the flexible substrate while emitting a laser beam thereto.
