Abstract
A display device has a plurality of sub-pixels, and includes a circuit substrate, a plurality of micro light-emitting semiconductor elements, a light conversion layer and an opposite substrate. The micro light-emitting semiconductor elements are disposed separately on the circuit substrate and configured corresponding to the sub-pixels. The light conversion layer has a plurality of light conversion portions disposed respectively corresponding to at least partial of the micro light-emitting semiconductor elements. The light emitted from the micro light-emitting semiconductor element corresponding to the sub-pixel passes through the light conversion portion to generate white light. The opposite substrate is disposed at one side of the light conversion layer away from the circuit substrate. In another display device, the light emitted from the micro light-emitting semiconductor element passes through the light conversion layer to generate white light.
