The invention provides a holographic display element, holographic display glass and a vehicle. The holographic display element comprises a holographic display function layer and base material layers arranged on the two opposite sides of the holographic display function layer. The holographic display element satisfies the following conditions: F = T * a, F > = 240; wherein F represents the flatness of the holographic display element, T represents the thickness of the holographic display element in the stacking direction of the holographic display element, and a represents the ratio of the transverse tensile strength of the base material layer to the longitudinal tensile strength of the base material layer. The holographic display element is limited to meet F = T * a and F > = 240, and the thickness of the holographic display element, the transverse tensile strength of the base material layer and the longitudinal tensile strength of the base material layer are limited, so that wrinkles of the holographic display element are reduced, the display effect of the holographic display glass is improved, and the safety performance of the holographic display glass applied to vehicle driving is improved.

    本申请提供了全息显示元件、全息显示玻璃及车辆。全息显示元件包括全息显示功能层、及设于全息显示功能层相对两侧的基材层。全息显示元件满足以下条件:F=T*a,F≥240;其中,F代表全息显示元件的平整度,T代表沿全息显示元件的层叠方向上全息显示元件的厚度,a代表基材层的横向拉伸强度与基材层的纵向拉伸强度的比值。本申请通过限定全息显示元件满足F=T*a,F≥240,限定全息显示元件的厚度、基材层的横向拉伸强度、及基材层的纵向拉伸强度,以减少全息显示元件褶皱的产生,提高全息显示玻璃的显示效果,提高全息显示玻璃应用在车辆驾驶中的安全性能。
