Abstract: Disclosed is a blade shell section of a wind turbine blade, such as wind turbine blade with a flatback section. The blade shell section extends in a longitudinal direction from a first shell section position to a second shell section position. The blade shell section comprises a first laminate layer forming the outer surface of the blade shell section and a second laminate layer forming the inner surface of the blade shell section. The blade shell section further comprising a first shell section and a corner shell section between the contour shell section and the flatback shell section.
