Abstract
A dart board display device includes a reflection board having with an inner polarization board connected thereto, an inner glass board connected to the inner polarization board and an inner circuit board connected to the inner glass board. A liquid crystal display board is connected to the inner circuit board and an outer circuit board is connected to the liquid crystal display board. An outer glass board is connected to the outer circuit board and an outer polarization board is connected to the outer glass board. The inner polarization board and the outer polarization board are both rotated 90 degrees so as to obtain light points on the liquid crystal display board.
