    Abstract: The present invention discloses an electroluminescent display and a display device, the electroluminescent display comprising a base substrate and a plurality of pixel units arranged in arrays on the base substrate. Each pixel unit is composed of at least four subpixel units, and each pixel unit comprises at least three luminescent material layers. Each luminescent material layer at least covers two adjacent subpixel units, and only one luminescent material layer in each subpixel unit emits light. Since each luminescent material layer at least covers two adjacent subpixel units, when a luminescent material is evaporated and coated by an evaporation coating process, the subpixel units can be made smaller with the size of the mask plate unchanged, which is helpful for improving the resolution of the display.
