Abstract: A flexible display device is configured to be bendable along at least one bending axis, have two opposite sides at both ends of the bending axis, respectively, and include a first substrate and a second substrate opposite to each other, and a hetero-shaped double-sided adhesive tape bonding the first substrate and the second substrate to each other on at least one of the two opposite sides. The hetero-shaped double-sided adhesive tape includes a lower adhesive layer, a base material layer, and an upper adhesive layer which are stacked together in sequence. In a stacking direction of the lower adhesive layer, the base material layer and the upper adhesive layer, the upper adhesive layer has a non-overlapping region that does not overlap the lower adhesive layer, and/or the lower adhesive layer has a non-overlapping region that does not overlap the upper adhesive layer.

Abstract: Disclosed are a display unit, a display panel, a display device and an optical information storage device. The display unit comprises a photochromic thin film and an optical filter thin film on a side of the photochromic thin film. The photochromic thin film presents a colored state under an irradiation of a first preset light, and presents a transparent state under an irradiation of a second preset light. A wavelength range of the first preset light is different from that of the second preset light. The optical filter thin film is a one-way optical filter thin film that is substantially transparent to lights coming from a photochromic thin film side, and functions as an optical filter to lights coming from a side opposite the photochromic side to allow the first preset light to pass through and to reflect lights of other wavelengths.
