摘要： A display device includes a light source, a light-directing element, a first lens, a microlens array, and a reflective display element. The light-directing element is adapted to project a lighting beam provided by the light source toward an incident direction. The first lens is configured to receive the lighting beam projected by the light-directing element and project the lighting beam toward the incident direction. The first lens is located between the microlens array and the light-directing element. The micro-image units of the reflective display element correspond to the microlenses of the microlens array respectively. Each micro-image unit converts the lighting beam into an sub-image beam and reflect the sub-image beam to the microlens array. Each sub-image beam is projected to the first lens by the corresponding microlens, and the sub-image beams pass through the light-directing element and transmit to an aperture to form an image beam.
