Abstract

A manufacturing method for LCD device, it is by illuminating laser beam on plurality of filtering sheets installed on transparency substrate to remove portion of filtering sheet. Form light-shield film on removed portion to surround the filtering sheet. Its features are: The laser beam supplied by laser oscillator is through: Beam expander for adjusting the beam radius of laser beam; Cylinder-shaped lens group for adjusting the vertical-horizontal ratio of beam shaping of laser beam emitted from beam expander; Energy distribution transferring device for uniform the energy density surrounding the optic axle of laser beam emitted from cylinder-shaped lens group. The beam-shaping component for shaping the beam-shape of laser beam emitted from energy distribution transferring device to compose optic system, and form removal portion with specified width on filtering sheet.
