Array substrate and manufacturing method thereof, display panel, display device, display kit

A display device, comprising:

• a display panel and a magnetic field generating device, the display panel comprising an array substrate and a color filter substrate disposed opposite to the array substrate,
• wherein the array substrate comprises a base substrate and a reflective layer located on a side of the base substrate away from the color filter substrate;
• wherein the reflective layer comprises a plurality of micro-capsules, each of the micro-capsules includes a plurality of absorbing particles and a plurality of reflecting particles;
• wherein the absorbing particles are magnetic particles absorbing light, and the reflecting particles are non-magnetic particles reflecting light;
• wherein the magnetic field generating device is on a side of the reflective layer away from the color filter substrate;
• wherein the magnetic field generating device comprises:
• a first electrically conductive coil, a first power supply and a first switch;
• wherein the first electrically conductive coil is connected in series with the first power supply and the first switch;
• and
• wherein an orthographic projection area of the first electrically conductive coil on the base substrate is entirely overlapped with an orthographic projection area of the reflective layer on the base substrate.
