A method for manufacturing a tubular body, includes: attaching a first member to an outer or inner peripheral surface of one end in an axial direction of a cylindrical core, along a circumferential direction of the peripheral surface thereof; applying a first resin solution on the peripheral surface, to cover it and the peripheral surface of one end of the first member closer to the center of the core, and to form a coating (first coat film); attaching a second member to the peripheral surface of the end of the first coat film on the side where the first member has been attached; applying a second resin solution on the peripheral surface of the first coat film, to cover it and the peripheral surface of the end of the second member closer to the center, and to form a coating (second coat film); peeling off the first and second members.

Method for manufacturing a tubular body

The present invention provides a display element, which is driven at a low voltage, displays a high-contrast image with few density irregularities, and has improved image holding property. In a display element, which displays an image by moving, between a first and second substrate, particles having different colors and charge polarities by an electric field applied between the first and second substrates, the surface roughness of at least one of the substrates is 1 nm to 1 &mgr;m, the coefficient of shape is to , the width and depth of the recessed part are not identical to the diameter of the particles and the contacting parts of the recessed part and the particles do not form a surface.
