ABSTRACT:
A checkerboard or a "go" board is implemented with a liquid crystal display or an electrochromic display. A pair of a disc pattern electrode and a ring pattern electrode are provided for showing a black "go" stone and a white "go" stone, respectively. A plurality of the disc pattern elecrodes and the ring pattern electrodes are formed on a first transparent glass substrate to serve as segment electrodes. A common electrode is provided opposite to the pair of the disc pattern electrode and the ring pattern electrode. The common electrode is arranged on the opposing second transparent glass substrate. A plurality of checks are printed on, for example, the first transparent glass substrate. The common electrodes, the disc pattern electrodes, and the ring pattern electrodes are activated by a driver coupled to a memory. The memory is adapted to store arrangement information of the black and the white "go" stones, and the blank indication.
