The second optical system is configured to form, in distance, an image conjugate to the first light emission region, and form, at the incident end, a third light emission region substantially conjugate to an exit pupil of the first optical system. The light deflection section is configured to continue to perform an operation that causes a direction in which the bundle of rays is deflected to be continuously changed.
