Display screen and manufacturing method thereof

A manufacturing method of a display screen, comprising following steps:

• a step B1:
• providing a mother board and at least one daughter board;
• a step B2:
• disposing a first conductive adhesive on the at least one daughter board, wherein a first adhesive force is formed between the first conductive adhesive and the at least one daughter board, wherein a material of the first conductive adhesive comprises a first matrix resin and a first conductor, and the first matrix resin comprises a polar group;
• a step B3:
• disposing a second conductive adhesive on the first conductive adhesive, wherein the second conductive adhesive is in direct contact with the first conductive adhesive, a second adhesive force is formed between the first conductive adhesive and the second conductive adhesive, a material of the second conductive adhesive comprises a second matrix resin and a second conductor, and the second matrix resin comprises another polar group;
• and
• a step B4:
• assembling the mother board and the at least one daughter board, wherein the first conductive adhesive and the second conductive adhesive are disposed between the mother board and the at least one daughter board, a third adhesive force is formed between the second conductive adhesive and the mother board, and both the first adhesive force and the second adhesive force are greater than the third adhesive force.
