Abstract: A stereoscopic display device including a barrier panel is provided. When a viewing distance of a viewer is out of the proper range, the stereoscopic display device may shift the blocking regions and the transmitting regions of the barrier panel. The stereoscopic display device may maintain the ratio of channels located within a barrier blocking region and a barrier transmitting region of the barrier panel by using the channels disposed within trigger regions of the barrier panel. Thus, the stereoscopic display device may provide a stereoscopic image of good quality to the viewer located at a region being out of the proper range.

Abstract: Disclosed are a display panel in which a unit pixel is divided into a wide-angle area and a narrow-angle area in which at least sub-pixel is disposed and light emission is individually and selectively performed, a display device including the same, and a manufacturing method thereof. A semi-cylindrical lens is disposed in the wide-angle area so as to cover a plurality of sub-pixels. Semi-spherical lenses are disposed in the narrow-angle area so as to cover sub-pixels respectively. Therefore, a direction of light emitting from a light-emitting layer is controlled by adjusting a refractive index of each of the lenses in the wide-angle area and the narrow-angle area. Thus, a viewing angle is controlled.
