There is provided an image display device including an image generating device (111), and a light guide unit (120). When a point at which light output from a center of the image generating device (111) is incident is a point O, a normal line passing through the point O in a portion of the unit is an X axis, an axis of the unit passing through the point O is a Y axis, an optical axis of light incident at the point O among light beams output from a center of the image generating device is a ¶ axis, and a virtual plane including the ¶ axis and the Y axis is a ¶Y plane, light output from the image generating device and incident at a point (0,Y 1 ,Z 1 ) forms an angle ¸ z with the ¶Y plane and forms an angle ¸ Y with an XZ plane, and when Z 1 ‰ 0, ¸ Z ‰ ¸ Y is satisfied. |
