Abstract

A display device apparatus provides an increased color reproduction rate and/or contrast ratio. The display device includes a first substrate; a second substrate disposed on the first substrate; and a liquid crystal layer arranged between the first substrate and the second substrate. A reflective layer is disposed on the first substrate, a polarizing layer is disposed on one surface of the second substrate, and a metasurface pattern layer is disposed on the second substrate. The metasurface pattern layer includes a third substrate and a first metasurface pattern disposed on the third substrate.
