Summary:The invention relates to a display device, which comprises a light source, a light guide element, a reflective display element and a micro lens array. The light source is used for providing an illumination light beam. The light guide element is arranged on the transmission path of the illumination light beam so as to project the illumination light beam towards a first direction. The reflective display element is used for receiving the illumination light beam projected by the light guide element. The reflective display device includes a plurality of micro-imaging units, wherein each micro-imaging unit is used for converting the illumination light beam into sub-image beams and reflecting the sub-image beams. The micro lens array is arranged on the transmission path of the sub-image light beams, wherein the light guide element is positioned between the micro lens array and the reflective display element. The micro lens array includes a plurality of microlenses. Each sub-image light beam penetrates through the li
