Abstract
An optical member includes a first liquid crystal assembly and a second liquid crystal assembly. The first liquid crystal assembly has a liquid crystal layer aligned in a first direction. Light polarized in the first direction is reflected from the first liquid crystal assembly. The second liquid crystal assembly is positioned on the first liquid crystal assembly. The second liquid crystal assembly has a liquid crystal layer aligned in a second direction that is opposite to the first direction. Light polarized in the second direction is reflected from the second liquid crystal assembly. Therefore, an image display quality is improved.
