Display device and display method

1. A display device comprising:

a timekeeping unit that keeps time; and

a display unit that displays numerals denoting the hour value of time information, numerals denoting the tens digit of the minute value of the time information, and numerals denoting the ones digit of the minute value of the time information at dispersed over the display area of the display device, and varies the position where time information is displayed by the numeral denoting the hour value, the numeral denoting the tens digit of the minute value, and the numeral denoting the ones digit of the minute value, based on time information kept by the timekeeping unit;

wherein the numeral denoting the hour value, the numeral denoting the tens digit, and the numeral denoting the ones digit are displayed on the display unit according to at least one of a specified display state and a specified display position;

wherein the numerals denoting the hour value, the numerals denoting the tens digit, and the numerals denoting the ones digit are displayed in a font size prescribed for the hour value, the tens digit, and the ones digit, respectively, the font size for the numerals denoting the hour value, tens digit, and ones digit each being different from one another; and

the numerals denoting the hour value, the numerals denoting the tens digit, or the numerals denoting the ones digit are disposed so that a part of the numerals extends outside the display area of the display unit and the numerals can be partially read.

2. The display device described in claim 1 , wherein:

prescribed information sequentially determined based on the time information is displayed in a first display state as the display state of the numerals denoting the hour value, the numerals denoting the tens digit, or the numerals denoting the ones digit; and

at least one of a before value and an after value, which are the values chronologically before and after the prescribed information, is displayed in the numerals denoting the hour value, the numerals denoting the tens digit, or the numerals denoting the ones digit in a second display state, which is a display state that is different from the first display state.

3. The display device described in claim 1 , wherein:

information that is not the prescribed information, the before value, or the after value is displayed in the numerals denoting the hour value, the numerals denoting the tens digit, and the numerals denoting the ones digit in a third display state, which is a display state different from the first and second display states.

4. The display device described in claim 1 , wherein:

the difference between the first display state and the second display state is a difference in the contrast of the display colors presented on the display unit or a difference in the hue of the display colors presented on the display unit.

5. The display device described in claim 1 , wherein:

the other of the before value and the after value is displayed in a display state other than the first display state and the second display state.

6. The display device described in claim 1 , wherein:

the numerals denoting the hour value, the numerals denoting the tens digit, and the numerals denoting the ones digit are displayed in display states prescribed for the hour value, the tens digit, and the ones digit, respectively.

7. The display device described in claim 1 , wherein:

the numerals denoting the hour value, the numerals denoting the tens digit, and the numerals denoting the ones digit are displayed in a display position prescribed for the hour value, the tens digit, and the ones digit, respectively.

8. The display device described in claim 7 , wherein:

the numerals denoting the hour value, the numerals denoting the tens digit, and the numerals denoting the ones digit are disposed so that the hour value, the tens digit, and the ones digit are disposed regularly substantially along a prescribed axis of the display unit.

9. The display device described in claim 1 , wherein:

the display unit is an electrophoretic display device.

10. The display device described in claim 1 , further comprising:

an annular case;

wherein the display unit is disposed to the case curving around the circumference of the case.

11. The display device described in claim 10 , wherein:

indications denoting chronologically identical information are disposed to the display unit at different locations.

12. A display method for displaying numerals denoting the hour value of time information, numerals denoting the tens digit of the minute value of the time information, and numerals denoting the ones digit of the minute value of the time information, comprising steps of:

displaying the numerals denoting the hour value, the numerals denoting the tens digit, and the numerals denoting the ones digit at positions dispersed over the display area of a display device;

varying the position where the time information is displayed by the numeral denoting the hour value, the numeral denoting the tens digit of the minute value, and the numeral denoting the ones digit of the minute value; and

displaying the numeral denoting the hour value, the numeral denoting the tens digit, and the numeral denoting the ones digit according to at least one of a specified display state and a specified display position;

displaying the numerals denoting the hour value, the numerals denoting the tens digit, and the numerals denoting the ones digit in a font size prescribed for the hour value, the tens digit, and the ones digit, respectively, the font size for the numerals denoting the hour value, tens digit, and ones digit each being different from one another; and

disposing the numerals denoting the hour value, the numerals denoting the tens digit, or the numerals denoting the ones digit so that a part of the numerals extends outside the display area of the display unit and the numerals can be partially read.

13. The display method described in claim 12 , wherein:

prescribed information sequentially determined based on the time information is displayed in a first display state as the display state of the numerals denoting the hour value, the numerals denoting the tens digit, or the numerals denoting the ones digit; and

at least one of a before value and an after value, which are the values chronologically before and after the prescribed information, is displayed in the numerals denoting the hour value, the numerals denoting the tens digit, or the numerals denoting the ones digit in a second display state, which is a display state that is different from the first display state.

14. The display method described in claim 12 , wherein:

the numerals denoting the hour value, the numerals denoting the tens digit, and the numerals denoting the ones digit are displayed in display states prescribed for the hour value, the tens digit, and the ones digit, respectively.

15. The display method described in claim 12 , wherein:

the numerals denoting the hour value, the numerals denoting the tens digit, and the numerals denoting the ones digit are displayed in a display position prescribed for the hour value, the tens digit, and the ones digit, respectively.
