Title:
METHOD FOR CHAMFERING SUBSTRATE, DEVICE FOR CHAMFERING SUBSTRATE AND PRODUCTION OF LIQUID CRYSTAL DEVICE
Document Type and Number:
Japanese Patent JP3257550
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a process for producing a liquid crystal display device which is capable of greatly ameliorating the processing variations and improving the efficiency and man-hours in a production process by transporting substrates in such a manner that the ridge line pressed to wheels advance in a direction reverse from the rotating direction of the wheels.
SOLUTION: A plurality of the diamond wheels 6 of a disk shape are integrally arranged to face the respective ridge line of the ridge line 4 and 5 of an electrode terminal 3 of the liquid crystal display device composed of the glass substrate 1 and the glass substrate 2 and diamond wheels 7 are installed on the opposite side. The liquid crystal display device composed of the glass substrates 1 and 2 is transported by a transporting belt, etc. At the time of this transportation, the ridge line parts 4 and 5 of the electrode terminal 3 are pressed to the diamond wheels 6 and 7 in such a manner that the stresses on the ridge line parts of the electrode terminal 3, are evenly distributed. The ridge line parts 4 and 5 of the electrode terminal 3 are both subjected to fine chamfering after the liquid crystal display device passes a diamond wheel section in the manner described above.
