Abstract: The display device of the present invention includes, in the following order toward a viewer: a display panel; a semi-transparent mirror; a Pancharatnam-Berry lens configured to cause one-handed circularly polarized light incident thereon that is left-handed circularly polarized light or right-handed circularly polarized light to converge while causing opposite-handed circularly polarized light incident thereon to diverge; and a circularly polarized light-selective reflector.

Abstract: A top-emitting subpixel structure may include at least one bank structure defining a plurality of emissive areas, and an emissive structure located in each emissive area. The subpixel structure may have a subpixel length and a subpixel width less than the subpixel length, a ratio of the subpixel length to the subpixel width defining a subpixel aspect ratio. Each emissive area may have an emissive area length and an emissive area width shorter than the emissive area length, a ratio of the emissive area length to the emissive area width defining an emissive area aspect ratio. The subpixel length may define a primary axis when the subpixel aspect ratio is greater than the emissive area aspect ratio; otherwise, the emissive area length may define the primary axis. At least a majority of the emissive areas may be arranged successively widthwise along a secondary axis perpendicular to the primary axis.
