Abstract:
A near-eye light field display device includes a display element, a microlens array and an optical element. The display element has a plurality of micro-image units and each of the plurality of micro-image units is configured to provide an elemental image beam. The microlens array is disposed in front of the display element and has a plurality of microlenses corresponding to the plurality of the micro-image units respectively. The optical element is disposed in front of the microlens array and located on a transmission path of the elemental image beams from the microlenses. An Abbe number of the microlens array is VdMLA, a refractive index of the microlens array is ndMLA, an Abbe number of the optical element is VdOE, a refractive index of the optical element is ndOE, and the microlens array and the optical element meet at least one of: VdOE>VdMLA and ndOE
