Abstract
The present invention provides a light-shielding structure, a method for manufacturing the structure, a display device and a method for displaying with the display device. Said light-shielding structure comprises a plurality of micro light-shielding boxes, each of the micro light-shielding boxes comprises a sealed cavity provided with a transparent solvent, a first electrode and a second electrode disposed oppositely, and at least one rotator disposed between said first electrode and said second electrode. Said rotator comprises a light-shielding portion and a transparent portion, and said light-shielding portion has an electrical property different with that of said transparent portion. The light-shielding structure in the embodiments of the present invention comprises at least one rotator, which is controlled to rotate by means of the electrodes at two sides thereof. When the light leakage region in the color film substrate needs light shielding, at least one rotator is controlled to form a light-shielding band to shield the light leakage region of the color film substrate; when it does not need light shielding, the at least one rotator is controlled to rotate such that the forme…
