An image display system includes a display provided on an interior surface of a vehicle body structure, including a front pillar, and a camera that captures an image of an extended region including an image of a blind spot region outside the vehicle body structure. When the door is in a closed state, the image display system causes the display to display the image of the blind spot region. The image of the blind spot region is generated based on the image of the extended region captured by the camera, by extracting, from the image of the extended region, the image of the blind spot region in a shape of the display. An interior surface of the front pillar includes a curved shape. The display is provided in the interior surface of the front pillar along the curved shape of the interior surface of the front pillar.
