ABSTRACT:
A display device including: a first substrate having a pixel electrode; a second substrate having a common electrode; a microcapsule sandwiched between the first substrate and the second substrate; and a display material changing its optical characteristic in response to an electrical stimulation, the display material being encapsulated in the microcapsule, the microcapsule being selectively disposed on a display area formed by the pixel electrode in between the first substrate and the second substrate, and a background area of one of the first substrate and the second substrate being colored with a background color, the background area serving as a background with respect to the display area.
