  In the technique described in Patent Document 1 described above, an electronic paper device is provided to display arbitrary display contents on the handrail of the escalator. When an electronic paper device is mounted on an escalator handrail that continues to rotate endlessly, the electronic paper device is flexible enough to handle bending at the time of a U-turn as it rotates, and every time it makes a U-turn. Although durability against bending and returning from bending repeatedly is required, the electronic paper device described in Patent Document 1 cannot satisfy these flexibility and durability.

  The object of the present invention is to solve the above-mentioned problems, and to provide flexibility to cope with bending at the time of U-turn and durability against repeated action of bending and returning from bending each time it makes a U-turn. An endless belt and a rotating carrier are provided.

  As a preferred example of the endless belt of the present invention, the display medium is a group of particles including particles that can be electrically driven and have optical reflectance, and the flexible substrate is divided into a plurality of spaces by partition walls. In addition, the adhesive composition for bonding the partition wall and the flexible substrate comprises an elastomer that is liquid at room temperature, an acrylic and / or methacrylic compound, a photoradical generator, and a thermal radical generator. It has photocurability with acrylic and / or methacrylic compounds and photoradical generators, and thermosetting with liquid elastomers and thermal radical generators, and is formed by radical polymerization of acrylic and / or methacrylic compounds by light irradiation.

  The feature of this embodiment is that the adhesive 9 used when a panel structure that can be bent in at least one direction is formed by bonding two substrates bent in at least one direction in FIGS. It is in the adhesive composition. 7 (a)-(c), as shown in the example in which one cell forming partition (partition member) is provided between the partitions arranged as the inter-substrate gap securing member, 1) It is formed corresponding to a plurality of cells 7 (in this example, 2 × 2 = 4 cells 7 as shown in FIG. 7C when the panel is viewed from above), and between desired substrates In a portion other than the inter-substrate gap securing member 4-1, which has a height corresponding to the gap and holds the inter-substrate gap of the information display panel, and (2) the inter-substrate gap securing member 4-1. This embodiment is also implemented in that it is formed of a partition wall portion (cell forming partition member) 4-2 for forming each cell 7 of the information display panel having a gap 8 between the substrates 1 and 2. There are example features. Here, an example is shown in which the position of the gap 8 is the center between the substrates. In the present embodiment, the inter-substrate gap securing member 4-1 is formed on the substrate 1 at a height corresponding to the desired inter-substrate gap, and the gap 8 for partitioning the other inter-substrate space into the cells 7 is formed. The length of the partition members 4-2-1, 4-2-2 at the position where the partition members 4-2 having the both substrates 1, 2 are opposed to each other and overlap each other is the inter-substrate gap. It is formed to be less than the length of the securing member 4-1, and the adhesive 9 is disposed only between the top of the inter-substrate gap securing member 4-1 and the substrate 2, and the other substrate 2 is attached. The panel structure is combined.

  In the embodiment of the information display panel shown in FIGS. 1A to 1C to 7A to 7C, substrates other than the inter-substrate gap securing member 4-1 provided for securing the inter-substrate gap are used. A gap 8 between the partition members 4-2-1 and 4-2-2 for partitioning the interspace into cells 7 or a gap 8 between the partition member 4-2 and the substrate 1 or 2 is formed. Thus, a non-bonded portion between the two substrates 1 and 2 is provided, and preferably the minimum unit of the non-bonded portion is set to 2 × 4 or more or 3 × 3 or more in the lattice arrangement of cells. It is easy to get. In the embodiment of the information display panel shown in FIGS. 1 (a)-(c) to 7 (a)-(c), the adhesive composition according to the present invention is disposed on the top of the inter-substrate gap securing member. Thus, the observation surface side substrate and the back surface side substrate are bonded together.

  In an information display panel of a type in which a display medium configured as a particle group is reversed in the vertical direction between the opposing substrates 1 and 2, the inter-substrate space other than the inter-substrate gap securing member 4-1 is defined as the cell 7. The non-joined portion (gap 8) between the two substrates formed in the partition wall portion (cell forming partition member) 4-2 for partitioning into two, for example, as shown in FIGS. 1 (a)-(c) It is preferable to form between partition members 4-2-1 and 4-2-2, particularly in the vicinity of the center between the substrates. This is a structure in which there is a gap 8 between the partition member 4-2 and the substrate 1 or 2 near the starting point of the reversal movement of the particles. When the particles move, the particles move from the gap 8 to the adjacent cell 7. This is because the arrangement distribution of the particle groups serving as the display medium in the entire screen is varied and the display image quality is likely to be deteriorated.

  The gap 8 of the partition member 4-2 described above is preferably set to be equal to or smaller than the average particle diameter of the particle group used as the display medium. As a result, the particles constituting the display medium are sufficiently prevented from moving to the adjacent cell 7, and a non-joined portion (having a slight gap 8) between the two substrates is formed, thereby displaying information. The flexibility of the panel (panel structure) is maintained.

  The arrangement of the partition portion (cell forming partition member) 4-2 for partitioning the inter-substrate gap securing member 4-1 and other inter-substrate spaces into the cells 7 is a lattice shape, but the cross-sectional shape of the cell 7 is Any of polygons such as quadrangle, triangle, and hexagon, circles, ellipses, and racetracks may be used, or a plurality of shapes may be combined. A rectangular shape is preferable from the viewpoint of increasing the aperture ratio of the region, and a shape having a curve is preferable from the viewpoint that particles constituting the display medium can be easily moved. From the above viewpoint, a square with rounded corners is preferably used.

However, the back side substrate 1 may be bent in at least one direction even if it is not a transparent substrate, and the back side electrode 5 may be flexible even if it is not transparent. In addition, the observation surface side substrate and the back surface side substrate may have a configuration opposite to the example illustrated in FIGS. 8A to 8C and FIGS. 9A to 9C.
