## Abstract

A vehicle display device includes an image display device having a display surface that displays an image, an optical system that projects display light of the image toward a reflection surface in front of a driver, and a control unit, wherein the display surface includes a first region and a second region, wherein the control unit causes the image display device to display a first image when a display position of the image is in the first region, and causes the image display device to display a second image when a display position of the image is in a boundary between the first region and the second region, and wherein the second image is an image having a pattern different from a pattern of the first image, and has a configuration in which a low luminance portion and a high luminance portion are combined.

## Claims

### Claim 1

A vehicle display device comprising:
an image display device having a display surface that displays an image;
an optical system that projects display light of the image toward a reflection surface in front of a driver; and
a control unit that controls the image display device, wherein
the display surface includes a first region that is a region visually recognized by both eyes of the driver and a second region that is a region at a further end of the display surface in an image lateral direction relative to the first region,
the control unit causes the image display device to display a first image when a display position of the image is in the first region, and causes the image display device to display a second image when a display position of the image is in a boundary between the first region and the second region,
the second image is an image having a pattern different from a pattern of the first image, and has a configuration in which a low luminance portion and a high luminance portion are combined,
the first image is an image of one figure, and
the second image is an image of a figure having a configuration in which a plurality of elements is disposed.

### Claim 2 (depends on 1)

The vehicle display device according to claim 1, wherein
the second image is divided into the plurality of elements disposed in the image vertical direction,
or the second image is divided into the plurality of elements by division lines inclined with respect to the image vertical direction,
or the second image is divided into the plurality of elements disposed in the image lateral direction,
or the second image has a plurality of element groups disposed in the image vertical direction, the plurality of element groups extends in the image lateral direction and has the plurality of elements disposed in the image lateral direction.

### Claim 3 (depends on 1)

The vehicle display device according to claim 1, wherein
a gap is provided between the adjacent ones of the elements.

### Claim 4 (depends on 1)

The vehicle display device according to claim 1, wherein
the second image is an image having gradation in which luminance changes along an image lateral direction.

### Claim 5 (depends on 4)

The vehicle display device according to claim 4, wherein
the luminance in the gradation of the second image decreases toward a boundary line between the first region and the second region.
