The light from the light source (52) reflected by the spatial light modulator (30) is irradiated to the front of the unit via the projection lens (72), and a light shielding member (32) for shielding a part of the reflected light from the reflection control unit (30A) is disposed on the front side of the unit of the spatial light modulator (30). At this time, the light-shielding member (32) has a configuration in which an opening (32a) is formed, the opening (32a) having an opening shape in which an isosceles trapezoid is inverted up and down, and the left-right width of a non-light-shielding region, which does not block the reflected light from the reflection control unit (30A), is narrower at the lower part than at the upper part.
构成为将由空间光调制器(30)反射后的来自光源(52)的光经由投影透镜(72)向单元前方照射,并且在空间光调制器(30)的单元前方侧配置有对来自反射控制部(30A)的反射光的一部分进行遮光的遮光部件(32)。此时,作为遮光部件(32),采取形成有开口部(32a)的结构,开口部(32a)具有使等腰梯形上下反转而成的开口形状,使不遮挡来自反射控制部(30A)的反射光的非遮光区域的左右宽度在下部比在上部变窄。
