The invention discloses a laminated light-emitting diode (LED) display screen and an LED-technology-based stereoscopic display, which relate to the display field. The laminated LED display screen comprises an LED display array, wherein the LED display array comprises at least two groups of LED display sub-arrays; and a first LED display sub-array and a second LED display sub-array are arranged on a front layer and a back layer. The number of LED components arranged in the same thickness can be effectively decreased, and difficulty in production can be effectively reduced. An LED display array of the stereoscopic LED display comprises at least two groups of LED display sub-arrays, wherein a first LED display sub-array and a second LED display sub-array are arranged on an upper layer and a lower layer. The stereoscopic LED display further comprises an LED substrate, wherein the LED display sub-arrays are arranged on the LED substrate which is made from a transparent material; and a transparent part is arranged on the periphery of the LED substrate. The LED components of the LED display array simultaneously have three dimensions, and can display stereoscopic pictures.
