Display and display device

An electronic device, comprising:

• a display, the display comprising:
• a circuit board structure comprising a first circuit board and a second circuit board;
• the first circuit board having a carrying region and an electrical connection region, and a first pad being disposed on the electrical connection region;
• the second circuit board having a first region and a second region, the first region being arranged on the electrical connection region of the first circuit board and being electrically connected to the first pad, and the second region being configured to be electrically connected to a driving terminal;
• and a rigidity of the second circuit board being less than a rigidity of the first circuit board;
• and
• a display substrate located on the carrying region of the first circuit board, the display substrate comprising a silicon substrate, a driving circuit and a second pad;
• at least part of the driving circuit being embedded in the silicon substrate;
• the driving circuit comprising a transistor having a semiconductor layer, and the semiconductor layer being located inside the silicon substrate;
• the second pad being electrically connected with the driving circuit, and the second pad being electrically connected with the first pad.
