Abstract: A display device includes a first substrate, a first electrode on a first surface of the first substrate, a first polarizing plate on a second surface of the first substrate which faces the first surface, a liquid crystal layer on the first electrode, a second polarizing plate on the liquid crystal layer, a color conversion layer on the second polarizing plate, the color conversion layer including a plurality of color conversion portions, and a second substrate on the color conversion layer. The first polarizing plate includes a first polarizer, a phase compensation layer and a second polarizer which are sequentially disposed, and an absorption axis of the first polarizer and an absorption axis of the second polarizer are parallel to each other.

Abstract: An optical film may include a polarizer configured to linearly polarize a first light to provide a linearly polarized light component. The optical film may further include a first semi-transmissive film overlapping the polarizer, configured to transmit the linearly polarized light component, and configured to reflect a first circularly polarized component of a second light. The first circularly polarized component of the second light may have a first wavelength. The optical film may further include a second semi-transmissive film overlapping the first semi-transmissive film, configured to transmit the linearly polarized light component, and configured to reflect a second circularly polarized component of the second light. The second circularly polarized component of the second light may have a second wavelength that is unequal to the first wavelength.
