Claim 7:
8. The image display device according to claim 6,
wherein a direction of a slow axis of the first λ/4 plate at an intersection of the straight line L and the first λ/4 plate is orthogonal to a direction of a slow axis of the second λ/4 plate at an intersection of the straight line L and the second λ/4 plate in a case of being observed in a direction in which the straight line L extends,
a direction of the slow axis of the first λ/4 plate at an intersection of the virtual line L1 and the first λ/4 plate is orthogonal to a direction of the slow axis of the second λ/4 plate at an intersection of the virtual line L1 and the second λ/4 plate in a case of being observed in a direction in which the virtual line L1 extends,
a direction of the slow axis of the first λ/4 plate at an intersection of the virtual line L2 and the first λ/4 plate is orthogonal to a direction of the slow axis of the second λ/4 plate at an intersection of the virtual line L2 and the second λ/4 plate in a case of being observed in a direction in which the virtual line L2 extends,
a direction of the slow axis of the first λ/4 plate at an intersection of the virtual line L3 and the first λ/4 plate is orthogonal to a direction of the slow axis of the second λ/4 plate at an intersection of the virtual line L3 and the second λ/4 plate in a case of being observed in a direction in which the virtual line L3 extends, and
a direction of the slow axis of the first λ/4 plate at an intersection of the virtual line L4 and the first λ/4 plate is orthogonal to a direction of the slow axis of the second λ/4 plate at an intersection of the virtual line L4 and the second λ/4 plate in a case of being observed in a direction in which the virtual line L4 extends.
