Abstract
A display unit includes a transparent hollow tube member and at least one display element sealed in the transparent hollow tube member. The display element is capable of rotating independently in the hollow tube member. Also, the display element has a surface which is divided into a plurality of areas having different colors and is polarized to have at least two poles having a different electrification state. An image formed by a display device including the display units is kind to the eye in the same way as printed matter, and does not cause eyestrain due to flickering of emitted light.

12. A method for producing a display device including at least one display unit, comprising the steps of:
-
forming a fiber having a three-layer structure including an outermost layer, an innermost layer, and an intermediate layer, said intermediate layer formed generally between, and co-axially with, said outermost layer and said innermost layer;
dissolving said intermediate layer of said fiber;
sealing an end portion of said fiber to form a display unit comprising said innermost layer of said fiber freely rotatable in said outermost layer of said fiber; and
arranging a plurality of said display units over substantially the entire display region of a display region of said display device, wherein said innermost layer of said fiber functions as a display element and said outermost layer of said fiber functions as a hollow tube member. - View Dependent Claims (13, 14, 15)
