METHOD FOR ARRANGING OPTICAL SHEET

摘要

PROBLEM TO BE SOLVED: To solve problems that a plurality of optical sheets provided with a back-light device tend to cause wrinkles thereon by static electricity generated between the optical sheets and a difference in extension of the optical sheets.

SOLUTION: The optical sheets are arranged in a manner that a reflection polarizing sheet and an optical sheet other than the reflection polarizing sheet are arranged adjacent to each other in a normal direction of a surface in a state capable of separating with each other so that a transmission axis direction of the reflection polarizing sheet and a direction in which a coefficient of linear expansion approximates the transmission axis direction of the reflection polarization sheet among the in-plane directions of the other sheet becomes approximately the same.
