- a dual-view display device and a method of fabricating the same wherein at least one of the plurality of light-transmissive regions of the parallax barrier corresponds to a light-refracting element that is in contact with the parallax barrier, Fully covering the corresponding light-transmitting region and extending along the extending direction of the light-transmitting region, the light-refracting element is disposed through the light-transmitting region corresponding to the parallax barrier, and the light-refracting element is in close proximity to the parallax screen Compared with the existing dual-view display device, it can significantly reduce the angle of the central crosstalk region without changing the left and right viewing angles, thereby improving the dual-view display effect of the dual-view display device and improving The viewer's viewing experience.
