Abstract
In a reflection-type image display for use in an image projection apparatus, when normal vectors of a pixel reflection surface in image display and non-display states are VA and VB, respectively, a Y axis is set in a normal direction of an image display surface with the pixel center as an origin, an X axis is set in a direction perpendicular to the Y axis and the normal vector VA, and a projection of the vector VB onto an XY plane is vb, the projection vb is at a predetermined angle not parallel to the Y axis, and among projections of illumination light incident on the pixel reflection surfaces onto the XY plane, a projection forming a maximum angle with respect to the Y axis exists only on a side with respect to the Y axis where a region in which the projection vb exists lies.
