摘要：
A transmissive display device which includes a display panel having multiple picture elements (5), a first array of microlenses (1) disposed on the incident side of the display panel, the microlenses each being disposed in correspondence to respective picture elements, a second array of microlenses (2) disposed on the outlet side of the display panel, the mcirolenses each being disposed in correspondence to respective picture elements, wherein the positions of the focal points of the first array of microlenses are identical with the positions of the focal points of the second array of microlenses, and wherein the focal length of each microlens in the first array is larger than that of each microlens in the second array.
