Optical filter and method of manufacturing same
First Claim
1. An optical filter comprising:
- a tempered glass substrate having a thickness of 0.05 mm to 0.3 mm; and
an optical filter formed on upper and lower surfaces of the tempered glass substrate,wherein a strengthening resin layer is formed on either one or both of the upper and lower surfaces of the tempered glass substrate in a manner being interposed between the tempered glass substrate and the optical filter layer, andthe resin layer is configured in a thickness of 0.1 μ
m to less than 5 μ

Abstract
Disclosed is an optical filter and a method of manufacturing the same, the optical filter including a tempered glass substrate and an optical filter formed on upper and lower surfaces of the tempered glass substrate and the method including: forming a sheet-cutting portion on a base glass substrate on a per-cell basis; tempering the base glass substrate such that upper and lower surfaces of the base glass substrate are tempered and a side portion thereof is tempered through the sheet-cutting portion as well; forming an optical filter layer on each of upper and lower surfaces of the base glass substrate; and dividing the base glass substrate into cells where each cell serves as a cell-based optical filter.

10. A method of manufacturing an optical filter, the method comprising:
-
forming a sheet-cutting portion on a base glass substrate having a thickness of 0.05 mm to 0.3 mm on a per-cell basis; tempering the base glass substrate such that upper and lower surfaces thereof are tempered and a side portion thereof is tempered through the sheet-cutting portion as well; forming an optical filter on each of upper and lower surfaces of the base glass substrate; and dividing the base glass substrate into cells where each cell serves as a cell-based optical filter, wherein, after tempering of the base glass substrate, a strengthening resin layer is formed on either one or both of the upper and lower surfaces of the base glass substrate in a manner being interposed between the base glass substrate and the optical filter layer, and the resin layer is configured in a thickness of 0.1 μ
