Claim:
1. An image display apparatus comprising: (A) an image generating device including a light source and a transmissive spatial light modulating device formed with pixels arranged in a two-dimensional matrix; and (B) a light guiding unit that guides light from the image generating device and emits the light toward an eye of a viewer, wherein the transmissive spatial light modulating device includes, on a light emitting side thereof, a microlens array including a microlens corresponding to each pixel, and when an incident solid angle of light entering a pixel from the light source is assumed to be ω wherein when a point at which light emitted from center of the image generating device enters the light guiding unit is assumed to be a point O, a normal in a portion of the light guiding unit passing through the point O is assumed to be an X-axis, an axis line of the light guiding unit in the portion of the light guiding unit passing through the point O is assumed to be a Y-axis, an optical axis of the light that is emitted from the center of the image generating device and enters the light guiding unit at the point O is assumed to be a ζ-axis, and a virtual plane including the ζ-axis and the Y-axis is assumed to be a ζ-Y plane, light that is emitted from the image generating device and enters the light guiding unit at a point (0, Y in a case of Z a value of θ
