Abstract
A near-eye light field display device, including a display element, a micro-lens array, a first shielding element, and a second shielding element, is provided. The display element is configured to provide an image beam. The micro-lens array is located on a transmission path of the image beam. The micro-lens array has multiple micro-lenses connected to each other. The first shielding element is located between the display element and the micro-lens array, and the first shielding element includes multiple first shielding regions. The micro-lens array is located between the first shielding element and the second shielding element. The second shielding element includes multiple second shielding regions. The first shielding regions and the second shielding regions are located on the transmission path of the image beam passing through a junction of the micro-lenses, and a ratio of diameter of the micro-lenses and a lens pitch of the micro-lenses is less than 0.8.
