Laser machining is widely used for display industry for annealing, cutting, repairing and patterning etc. When the materials are processed with laser, thermal effect caused by accumulation of residual energy leads material’s melting and side effect such as burr and micro-cracks eventually. On the other hand, ultrashort pulse laser machining has great advantage in screening such malfunction due to the fact that duration of laser pulse is extremely short so material can be effectively removed without giving redundant energy toward the material. There is high probability for so called, direct transition from solid to vapor by providing high peak power in ultrashort pico or femtosecond time frame. However, in reality, even ultrashort pulse laser processing leads well-known thermal effect causing by-products when excessive power is applied to process material with high speed and give no time for thermal relax. Recently, we have made great advance in processing display materials e.g. invar, glass, polyimide without having HAZ (heat affected zone) microscopically and macroscopic material’s deformation. Such advanced machining technology would contribute realizing very high resolution AMOLED display; UHD or AR/VR regime by providing nearly no HAZ and deformation even after massive ablation of material.
