<P>PROBLEM TO BE SOLVED: To provide a display device for allowing an observer to view an appropriate stereoscopic image in a wide range of place. Ž<P>SOLUTION: The display device includes: a display body having a plurality of pixels for emitting collimation light; and liquid optical elements arranged in front of the display body. The liquid optical element includes: two kinds of liquids with different refractive indexes, which are sealed in a fixed space; and three or more electrodes arranged in a portion of a surface sealing the liquids. The shape of the interface of the two kinds of liquids is changed in response to a voltage to be applied to the electrodes, thereby changing the direction of the collimation light in the display device.
