A display includes a first substrate, a first electrode, a second substrate, a second electrode and a display material layer. The first electrode is disposed on the first substrate and the second electrode is disposed on the second substrate. The display material layer is disposed between the first electrode and the second electrode. The display material layer of the invented display includes a solution and a plurality of first micro beads, wherein each of the first micro beads further has a plurality of different axis lengths in different axis directions, and the axis length in at least an axis direction is different from the axis lengths in the rest axis directions so that the first micro beads present different arrangement densities in different driving frequencies under the influence of polarized self-arrangement effect.

The present invention discloses a self-alignment manufacturing method of a microlens and an aperture using in an optical device. The method manufactures the aperture and the circular opening in the opaque film on a transparent substrate, and utilizes the self-alignment backside exposure technology to precisely integrate the aperture and the microlens made by macromolecule material without any combination step. The claimed method is simpler than conventional technology and can precisely align and integrate the microlens and the aperture with a continuous batch manufacture. Since the aperture and the circular opening are concentric circles and formed in same step, the microlens and the aperture can be precisely aligned with the backside exposure. The claimed invention can effectively improve the optical resolution and efficiency of the optical access and measurement devices.
