Zusammenfassung:	A three-dimensional hologram image display apparatus (2) displays a three-dimensional hologram image by use of computed interference fringe patterns. The three-dimensional hologram image display apparatus (2) includes a light modulation device (25) which has an electro-optical effect in which a refractive index is varied in accordance with an applied electric field intensity; and an electric field controller (22) configured to record computed interference fringe patterns in the light modulation device by varying an electric field intensity applied to the light modulation device in accordance with the computed interference fringe patterns.
