Abstract
A display device includes a light source, a light-directing element, a reflective display element, and a microlens array. The light-directing element is disposed on the transmission path of a lighting beam provided by the light source for projecting the lighting beam toward the first direction. The reflective display element includes a plurality of micro-image units, wherein each micro-image unit converts the lighting beam projected from the light-directing element into an sub-image beam and reflects the sub-image beam. The microlens array is disposed on the transmission path of the sub-image beams, wherein the light-directing element is located between the microlens array and the reflective display element. The microlens array includes a plurality of microlenses. Each sub-image beam pass throughs the light-directing element and is projected to an aperture by the corresponding microlens, and the sub-image beams pass through the aperture to form an image beam.
