wherein the first partial display region and the second partial display region each have display operation elements, each of which is able to change between a display operated state and a non-display operated state, respectively,

wherein the display operation elements of the first partial display region are aligned in a fixed direction on the first partial display region,

wherein the display operation elements of the second partial display region are aligned in another fixed direction on the second partial display region,

wherein a number of the display operation elements in the display operated state is changeable between a minimum value and a maximum value of a respective corresponding one of the rotation number ranges with an increase and a decrease of the rotation number,

wherein the first partial display region and the second partial display region are separated from each other on a meter display surface,

wherein the vehicle is a straddle type vehicle, and the meter display device is arranged at a center of the straddle type vehicle in a vehicle width direction,

wherein the second partial display region on the high speed side is arranged in an upper half portion of the meter display device,

wherein the second partial display region on the high speed side passes a center portion of the meter display device in the vehicle width direction and extends to both sides from the center portion of the meter display device in the vehicle width direction,

wherein the display operation element at a minimum value side of the second partial display region on the high speed side and the display operation element on a maximum value side of the first partial display region on the low speed side are located respectively so that a distance between the display operation element at the minimum value side of the second partial display region on the high speed side and the display operation element on the maximum value side of the first partial display region on the low speed side is longer than at least a length size of one rotation number character displayed or at least a length size of one display operation element,

wherein the display operation element at the minimum value side of the second partial display region on the high speed side is associated with a rotation number that is continuous from a rotation number associated with the display operation element on the maximum value side of the first partial display region on the low speed side,

wherein the display operation elements of the first partial display region are plural display segments, which are formed by dividing the first partial display region into a plurality of pieces in an arranged direction of the display segments of the first partial display region,

wherein the display operation elements of the second partial display region are plural display segments, which are formed by dividing the second partial display region into a plurality of pieces in an arranged direction of the display segments of the second partial display region,

wherein each of the display segments of the first partial display region and each of the display segments of the second partial display region is configured to be luminous and the number of the display segments which is luminous is changeable between the minimum value and the maximum value of the respective corresponding one of the rotation number ranges with the increase and the decrease of the rotation number,

wherein each of the display segments of the second partial display region has a larger area than each of the display segments of the first partial display region, respectively,

wherein the opening of the meter case is divided into an upper opening and a lower opening by a partition extending in a left-right direction, and

wherein the second partial display region is arranged in the upper opening, and the first partial display region is arranged in the lower opening.

2. The meter display device for a vehicle according to claim 1 ,

wherein the second partial display region includes a plurality of self-emitting light elements, each being configured to make each of the display operation elements luminous, and a number of the self-emitting light elements that emit light being configured to change in accordance with the increase and the decrease of the rotation number,

wherein the first partial display region includes mask elements configured to switch a transmission state and a non-transmission state of a common backlight for each of the display operation elements in accordance with the increase and the decrease of the rotation number, and

wherein the mask elements are shared between the rotation number and other information.

3. The meter display device for a vehicle according to claim 1 ,

wherein a length of each of the display segments of the second partial display region in the arranged direction of the display segments of the second partial display region is longer than a length of each of the display segments of the first partial display region in the arranged direction of the display segments of the first partial display region.

4. The meter display device for a vehicle according to claim 1 ,

wherein the arranged direction of the display segments of the first partial display region is parallel to the arranged direction of the display segments of the second partial display region.

5. The meter display device for a vehicle according to claim 1 ,

wherein a first rotation number width shown by each of the display segments of the first partial display region is smaller than a second rotation number width displayed by each of the display segments of the second partial display region.

6. The meter display device for a vehicle according to claim 1 ,

wherein each of the display segments in the second partial display region has a larger light emitting amount than each of the display segments in the first partial display region.
