Abstract: A display device includes a first substrate, a light emitting unit and a first micro lens unit. The light emitting unit is arranged on the first substrate to provide a light. The first micro lens unit is arranged on the light emitting unit to adjust the traveling direction of the light, wherein there is a distance from the light emitting surface of the light emitting unit to a position of half the height of the first micro lens unit, the first micro lens unit has an arc surface, the first micro lens unit has a height, and the arc surface has a curvature radius, and the distance and the curvature radius satisfy the relationship: 0.5H≤D≤3R1, where D represents the distance, H represents the height, and R1 represents the curvature radius.
