1. An illumination device comprising:
a first light guide having a first side surface, a second side surface located on a side opposite to the first side surface in a first direction, a first main surface, and a first opposed surface located on a side opposite to the first main surface in a second direction intersecting the first direction;
a first light source opposed to the first side surface to emit first P-polarized light to the first side surface;
a second light guide having a third side surface, a fourth side surface located on a side opposite to the third side surface in a first direction, a second main surface, and a second opposed surface located on a side opposite to the second main surface in the second direction; and
a second light source opposed to the third side surface to emit second P-polarized light to the third side surface,
the first side surface being inclined to the first main surface and the first opposed surface,
the first light source being inclined to a first straight line perpendicular to the first side surface,
the third side surface being arranged with the first side surface in the second direction,
the fourth side surface being arranged with the second side surface in the second direction and inclined to the second main surface and the second opposed surface,
the second light source being inclined to a second straight line perpendicular to the fourth side surface.
