Claim 5:
6. The image display device according to claim 5,
wherein a reflective linear polarizer, a first λ/4 plate, a half mirror, and a second λ/4 plate are provided between the polarizer A and the polarizer B in order from a side of the polarizer A,
the direction of the absorption axis of the polarizer A at the position X is parallel to a direction of a reflection axis of the reflective linear polarizer at an intersection between the straight line L and the reflective linear polarizer in a case of being observed in the direction in which the straight line L extends,
the direction of the absorption axis of the polarizer A at an intersection of the virtual line L1 and the polarizer A is parallel to a direction of the reflection axis of the reflective linear polarizer at an intersection of the virtual line L1 and the reflective linear polarizer in a case of being observed in the direction in which the virtual line L1 extends,
the direction of the absorption axis of the polarizer A at an intersection of the virtual line L2 and the polarizer A is parallel to a direction of the reflection axis of the reflective linear polarizer at an intersection of the virtual line L2 and the reflective linear polarizer in a case of being observed in the direction in which the virtual line L2 extends,
the direction of the absorption axis of the polarizer A at an intersection of the virtual line L3 and the polarizer A is parallel to a direction of the reflection axis of the reflective linear polarizer at an intersection of the virtual line L3 and the reflective linear polarizer in a case of being observed in the direction in which the virtual line L3 extends, and
the direction of the absorption axis of the polarizer A at an intersection of the virtual line L4 and the polarizer A is parallel to a direction of the reflection axis of the reflective linear polarizer at an intersection of the virtual line L4 and the reflective linear polarizer in a case of being observed in the direction in which the virtual line L4 extends.
