Provided is a spatial image display device capable of forming spatial images having a superior reality and high definition. A spatial image display deviceA is provided with: a display sectionincluding a plurality of pixels, and generating a two-dimensional display image corresponding to a video signal; a first lens arrayincluding a plurality of first lensesprovided in correspondence with the respective pixels, and allowing light passing through the respective pixelsto converge; and a second lens arrayconverting the converging light, which has passed through the first lens array, into parallel light or converging light, and allowing the converted light to pass therethrough. The light transmitting through the respective pixelsin the display sectionis directed to the second lens arrayafter being converged by the first lens array. Accordingly, the light entering the second lens arrayfrom the respective pixelsbehaves like light emitted from a point source, and is converted easily into the parallel light or the converting light in the second lens array
