A polarizer plate includes a base film, an adhesive layer disposed on one surface of the base film, a polarizer protection film disposed on one surface of the adhesive layer, a polarizer disposed on one surface of the polarizer protection film, and a cutting line formed perpendicular to the surface of the base film and configured to divide the polarizer protection film and the polarizer into separate regions.

Polarizer plate and display device including the same

A cholesteric liquid crystal reflective polarizing plate includes a cholesteric liquid crystal layer and a &#x3bb;/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 &#x3bb;/4 compensation layer includes a first &#x3bb;/4 compensation pattern which extends in the first direction and overlapping the first left-handed circularly polarizing portion, and a second &#x3bb;/4 compensation pattern which extends in the first direction adjacent to the first &#x3bb;/4 compensation pattern and overlaps the first right-handed circularly polarizing portion. The first &#x3bb;/4 compensation pattern and the second &#x3bb;/4 compensation pattern have slow axes perpendicular to each other.

Cholesteric liquid crystal reflective polarizing plate and liquid crystal display including the same

A reflective display device including: a reflection plate; a liquid crystal layer disposed on the reflection plate, the liquid crystal layer including a liquid crystal aligned vertically in an initial alignment state, a first phase delay layer disposed on the liquid crystal layer; a reflective polarizing element disposed on the first phase delay layer; and an absorptive polarizing element disposed on the reflective polarizing element, wherein external light incident on the absorptive polarizing element is in an unpolarized state.
