Abstract: A display device having an eyepiece is provided. The display device includes a display panel and an eyepiece. An image realized by the display panel may be provided to user through the eyepiece. An optical module may be disposed between the display panel and the eyepiece in order to increase a path of light. For example, the optical module may include a front quarter-wave plate, a half-mirror, a rear quarter-wave plate and a linear reflective polarizing plate, which are sequentially stacked. A positive C-plate may be disposed in the optical module. The light travelling toward the eyepiece from the display panel may pass through the positive C-plate. Thus, in the display device, the overall thickness may be reduced, and the viewing angle may be increased.

Abstract: A touch display apparatus is provided. In the touch display apparatus, a touch structure may be disposed on an encapsulating element covering a light-emitting device. A touch insulating layer may be disposed between a touch electrode and a bridge electrode of the touch structure. The touch insulating layer may include a guide opening on a path of light emitted from the light-emitting device. A side of the guide opening may be covered by the touch electrode. Thus, in the touch display apparatus, the front luminance may be improved.

Abstract: A polarization control panel capable of performing two-dimensional (2D) and three-dimensional (3D) control is discussed according to an embodiment. The polarization control panel includes a first substrate and a second substrate opposite to each other, and a first electrode and a second electrode disposed respectively on the first and second substrates. The polarization control panel further includes a lens layer disposed on the first electrode, the lens layer having a surface curved toward the second electrode, and the curved surface being rubbed in a first direction. The polarization control panel further includes an adhesive layer disposed on the second electrode and rubbed in a second direction, and an optically anisotropic layer disposed between the adhesive layer and the lens layer.
