Title:
GLASS SUBSTRATE SMOOTHING DEVICE
Document Type and Number:
Japanese Patent JP3726405
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a glass substrate smoothing device capable of flattening a substrate efficiently by uniformly grinding the entire surfaces of a glass substrate having coat film such as color filter substrate and locally raising the grinding level for those protruded parts caused by waviness or foreign matter.
SOLUTION: A glass substrate smoothing device comprises a grinding means 2 which grinds the surfaces of a glass substrate 1, a flexible stage 9 which fixedly supports the glass substrate 1, and a push up means 10 which partially push up the glass substrate 10 from the underside. Also the necessary protruded and nonuniformly coated parts in the glass substrate 1 located on the flexible stage 9 are raised from the underside so as to enable to selectively vary grinding level and sufficiently smoothen the parts in a specified processing time.
