摘要：A light-condensing device and a method of fabricating the same are provided. The light-condensing device includes a central block, a pair of vertical diffraction grating blocks respectively located left and right of the central block, and a pair of horizontal diffraction grating blocks respectively located above and below the central block. The vertical diffraction grating blocks include parallel vertical diffraction gratings in the form of lines extending in the direction of a vertical axis, and the horizontal diffraction grating blocks include parallel horizontal diffraction gratings in the form of lines extending in the direction of a horizontal axis.
