Head-up display for a motor vehicle comprising, inside a housing : - an image generation system ; - a first projection optical system comprising a first mirror and a second projection optical system comprising a second mirror ; the housing comprising an opening that is closed by a transparent window ; characterized in that : - said image generation system is designed to emit a first source light beam and a second source light beam that are spatially distinct from one another; - said first projection optical system and said second projection optical system are designed to project said first source light beam and second source light beam , respectively, outwardly through said transparent window , so as to form a first virtual image at a first projection distance and a second virtual image at a second projection distance in the field of view of a driver of said motor vehicle ; - said second projection optical system is designed to be passed through by a second intermediate light beam originating from the second source light beam ; - the first mirror is able, on the one hand, to intercept a portion of the second intermediate light beam and, on the other hand, to reflect said portion as a reflected portion ; - the head-up display comprises a masking piece interposed between the first mirror and the transparent window , and designed to stop said reflected portion . - an image generation system ; - a first projection optical system comprising a first mirror and a second projection optical system comprising a second mirror ; the housing comprising an opening that is closed by a transparent window ; characterized in that : - said image generation system is designed to emit a first source light beam and a second source light beam that are spatially distinct from one another; - said first projection optical system and said second projection optical system are designed to project said first source light beam and second source light beam , respectively, outwardly through said transparent window , so as to form a first virtual image at a first projection distance and a second virtual image at a second projection distance in the field of view of a driver of said motor vehicle ; - said second projection optical system is designed to be passed through by a second intermediate light beam originating from the second source light beam ; - the first mirror is able, on the one hand, to intercept a portion of the second intermediate light beam and, on the other hand, to reflect said portion as a reflected portion ; - the head-up display comprises a masking piece interposed between the first mirror and the transparent window , and designed to stop said reflected portion . - said image generation system is designed to emit a first source light beam and a second source light beam that are spatially distinct from one another; - said first projection optical system and said second projection optical system are designed to project said first source light beam and second source light beam , respectively, outwardly through said transparent window , so as to form a first virtual image at a first projection distance and a second virtual image at a second projection distance in the field of view of a driver of said motor vehicle ; - said second projection optical system is designed to be passed through by a second intermediate light beam originating from the second source light beam ; - the first mirror is able, on the one hand, to intercept a portion of the second intermediate light beam and, on the other hand, to reflect said portion as a reflected portion ; - the head-up display comprises a masking piece interposed between the first mirror and the transparent window , and designed to stop said reflected portion . <EOS>
