Title:
INSTRUMENT FOR MEASURING HEIGHT OF PROTRUDING DEFECT ON COLOR FILTER, AND REPAIR DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/011346
Kind Code:
A1
Abstract:
This invention relates to an instrument for measuring the height of a protruding defect on a color filter, and a repair device. For details, a color filter having, at the boundary portions between adjacent colored layers, protruding structures such as bulkheads formed by interlaminating the respective edge portions of the adjacent colored layers, wherein the protruding defect higher than the protruding structures is precisely measured by scanning with a stylus. For the purpose, the direction of the ridge line (304b, 504b) of the stylus (304a, 504a) is set into a direction intersecting with a scanning direction at 45º, and the length of the ridge line (304b, 504b) being set into a length (L) which allows the ridge line (304b, 504b) to simultaneously ride on two of the bulkheads (105) (protruding structures) separated from each other in the scanning direction. This allows scanning while the stylus (304a, 504a) is in contact with the tops of the bulkheads (105) without dropping onto the colored layers (101 to 103) respectively between the bulkheads (105) during scanning, so that with the tops of the bulkheads (105) as a reference height, the protruding defect (FA) higher than the reference height (H2) is measured.
