Abstract
(EN)
The layer thickness profile of the optical thickness of a first layer has a first monotonically increasing region, the first monotonically increasing region comprises a 1A monotonically increasing region having a maximum optical thickness less than or equal to 100 nm and a 1B monotonically increasing region having a minimum optical thickness greater than 100 nm, and a ratio 1B/1A of a slope 1B in the 1B monotonically increasing region to a slope 1A in the 1A monotonically increasing region is 0.8 or more but less than 1.5. The layer thickness profile of the optical thickness of a second layer has a second monotonically increasing region, the second monotonically increasing region comprises a 2A monotonically increasing region having a maximum optical thickness less than or equal to 200 nm and a 2B monotonically increasing region having a minimum optical thickness greater than 200 nm, and a ratio 2B/2A of a slope 2B in the 2B monotonically increasing region to a slope 2A in the 2A monotonically increasing region is more than 1.5 but less than 5.
