Abstract: A cholesteric liquid crystal reflective polarizing plate includes a cholesteric liquid crystal layer and a λ/4 compensation layer disposed on the cholesteric liquid crystal layer. The cholesteric liquid crystal layer includes a first left-handed circularly polarizing portion which extends in a first direction that include a left-handed cholesteric liquid crystal material, and a first right-handed circularly polarizing portion which extends in the first direction adjacent to first left-handed circularly polarizing portion and that includes a right-handed cholesteric liquid crystal material. The λ/4 compensation layer includes a first λ/4 compensation pattern which extends in the first direction and overlapping the first left-handed circularly polarizing portion, and a second λ/4 compensation pattern which extends in the first direction adjacent to the first λ/4 compensation pattern and overlaps the first right-handed circularly polarizing portion. The first λ/4 compensation pattern and the second λ/4 compensation pattern have slow axes perpendicular to each other.

Abstract: A method of attaching a polarizer includes preparing a first stage on which a display panel is disposed and a second stage on which a first polarizer is disposed, measuring a shape of a curl of the first polarizer; determining an attachment direction of the first polarizer with respect to the display panel based on the measured curl shape of the first polarizer and attaching the first polarizer to a first surface of the display panel by rotating at least one of the first stage and the second stage based on the determined attachment direction.
