Abstract

PURPOSE: To produce a substrate, which is excellent in liquid crystal directive characteristics, so as to improve the display quality of a liquid crystal display device of field effect type by forming the glass substrate with a number of flaws, which are arranged in a preset direction and in parallel, with the use of a laser beam.
CONSTITUTION: The laser beam 2 from a laser device 1 is diverged into parallel optical beam 5 by the use of lens systems 3 and 4 so that it may be changed into a diverged laser beam 8 by means of a reflecting mirror 6 and a slit 7. A glass substrate 9, which is being run in the direction of arrow 11 at a preset speed, is irradiated at a preset angle with the laser beam 8, which is being modulated, so as to form a plurality of flaws in the transparent electrode or insulating film. Incidentally, the modulation of the laser beam 8 is carried out such that the oscillatory output of the laser device 1 has its level adjusted with a short time cycle or such that pulse oscillations of high frequency effected
