--- Deleted all references to "IEC Q" and "QC" (see 4.3 of the:2008 edition);

--- Changed the definition of production line (see 3.1, 3:1 of the:2008 edition);

--- Deleted the term "changes in manufacturing" (see 3.3 of the:2008 edition);

--- Changed the definition of the term major change (see 3.3, 3:3:1 of the:2008 edition)

--- In Table 5, only the B1 group is retained for the test items (see Table 5, Table 5 of the:2008 edition);

--- In Table 7, only group B1 is retained in Group B (see Table 7, Table 7 of the:2008 edition):

This document is equivalent to IEC 61747-3:2015 "Liquid crystal display devices Part 3: Sectional specification for liquid crystal panels":

The following minimal editorial changes were made to this document:

--- Corrected the error in IEC Table 8, and only group B1 was retained in group B:
