Abstract
A substrate includes a base, a first electrode provided on the base, and a plurality of transparent organic patterns provided on the first electrode. Part or whole of each of a plurality of color sub-pixel regions of the substrate does not overlap with a region where each of the plurality of the transparent organic patterns is located. Microcapsules are scattered in each of the plurality of transparent organic patterns, and each of the microcapsules includes a capsule shell and light-absorbing particles and light-reflecting particles which are moveable in the capsule shell. Moving directions of the light-absorbing particles are substantially opposite to moving directions of the light-reflecting particles under an action of an electric field having an electric field direction perpendicular to the base, and the first electrode is included in electrodes forming the electric field.
