Image display device

1. An image display device comprising:

an image forming layer configured to form an image in an image display region; and

an image taking camera including an image taking lens,

the image forming layer including a backlight including a through-hole, an image taking window portion formed on a light path of the image taking camera in the image forming layer at a position overlapping the image taking lens when seen in plan view, and a frame portion defining a peripheral edge of the image taking window portion,

wherein the image taking camera is disposed on a back face side of the image forming layer and facing a display surface side of the image forming layer, at a position within the image display region when the image forming layer is seen in plan view, with the image taking lens positioned inside the through-hole, and

assume that a focal length of the image taking camera is d, a distance from a back face of the backlight to a tip of the image taking lens is G, an angle of view of the image taking camera is θ, a thickness of the backlight is D 1 , and a length of a frame of the backlight is B BL , an outer diameter φ STH of the frame portion satisfying a following condition;

φ STH ≥2*( d+G+D 1)tan(θ/2)+2* B BL .
