To provide a projector that suppresses a decline in a contrast ratio.
In a projector, a rotational angle φ0 of an alignment axis 49 of a liquid crystal layer, a rotational angle φ1 of a transmission axis 29 of an incident side polarizer, a rotational angle φ2 of a transmission axis 33 of a wire grid element, and a rotational angle φ3 of a transmission axis 36 of an emission side polarizer, with respect to a rotational angle of each axis from a reference direction on a reference plane when projecting on the reference plane orthogonal to a thickness direction of the liquid crystal layer, satisfy all of expressions: expression(1);44°≤φ0-φ2<45°or 45°<φ0-φ2≤46°, expression(2);f1≤φ1≤f2, f1=0.191×φ22+0.986×φ2-14.435, f2=-0.191×φ22+0.986×φ2+14.435, and expression(3); g1≤φ1≤g2, g1=0.064×φ33+0.841×φ33+1.525×φ33-1.46, g2=0.064×φ33-0.841×φ33+1.525×φ33+1.46.
