The substrate strip is provided to reduce the manufacturing cost by minimizing the dummy region and arranging many unit boards. The substrate strip(100) comprises the base substrate(110), a plurality of unit boards(120), the mold gate(140), and the dummy(130). The Base substrate is rectangular. The unit board is formed by dividing the base substrate. The mold gate is formed in a part of a plurality of unit boards positioned at the long side of the base substrate. The dummy is formed in the short side of the base substrate by dividing the Base substrate.
