1. A display apparatus comprising:
- a display member printed in gradations of color from a first color to a second color from one side of the member to other side;
an electro-optical display device having plural dot display sections disposed on the display member, each capable of allowing the light to transmit through and preventing the light from transmitting through; and
a driving circuit for selectively driving the plural dot display sections of the electro-optical display device to display data such as characters, images, etc. in gradations of color.

Abstract
A display apparatus is provided with a display member which is printed in gradations of color from a first color to a second color from one side of the member to other side, and an electro-optical display device having plural dot display sections disposed on the display member. The plural dot display sections are selectively driven, to display characters, images, etc. in gradations of color. The display apparatus which is simple in structure and low in manufacturing cost advantages to improve image and/or character discrimination and is used for an adornment purpose.

11. An electronic watch provided with a display apparatus which comprises:
-
a display member having a first area and a second area at least partially different from the first area, and printed in gradations of color from a first color to a second color from one side of the member to other side;
an electro-optical display device having plural dot display sections disposed on the display member, each capable of allowing the light to transmit through and preventing the light from transmitting through;
a time counting circuit for counting current-time data;
a driving circuit for driving the dot display sections disposed within an area corresponding to the first area of the display member to display data such as characters, images, etc. in gradations of color, when the current-time data counted by the time counting circuit is within a first period of time, and for driving the dot display sections disposed within an area corresponding to the second area of the display member to display data such as characters, images, etc. in gradations of color, when the current-time data counted by the time counting circuit is within a second period of time. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
