3.3 Polarizer Defects
Items Criteria
Scratch Linear
0.01 ≤ W ≤ 0.05, 1.0 ≤ L ≤ 10.0, N ≤ 4
Dent Circular
0.2 ≤ D ≤ 0.8, N ≤ 4
NOTE: D: Average Diameter D=(a+b)/2
W: Width, L: Length, N: Quantity
Linear: a>2b, Circular: a≤2b
a. Extraneous substances, which can be wiped out, like Finger
Print, Particles are not considered as a defect.
b. Defects which are on the Black Matrix (outside of Active Area)
are not considered as a defect.
