Abstract

The invention discloses a laser device. The laser device includes a light source generating a laser beam, a stage, and a lens assembly disposed between the light source and the stage and irradiating the laser beam to a substrate disposed on the stage. The lens assembly includes a first lens assembly making divergent the laser beam provided from the light source, a deflector changing a path of the laser beam provided from the first lens assembly, and a second lens assembly condensing the laser beam provided from the deflector and irradiating the condensed laser beam to the substrate.

Description

[0001] This patent application claims priority from Korean Patent Application No. 10-2020-0060999 filed on May 21, 2020, the contents of which are hereby incorporated by reference in their entirety. technical field [0002] The present disclosure relates to a laser device. More particularly, the present disclosure relates to a laser device for manufacturing a display device. Background technique [0003] Recently, demand for display devices has increased due to increased demand for portable electronic devices. Furthermore, as portable devices become complex, complex manufacturing processes are required. [0004] Among many other manufacturing processes, laser assisted manufacturing processes may be good candidates for manufacturing display devices. That is, the laser device can be used in the manufacturing process of the display device. In particular, laser devices are used for drilling, cutting, cleaning, marking, scanning, crystallization and surface modification of wor...
