A cell support frame is disposed on one side of each of a base plate and a circuit board aligned substantially on the same plane as the base plate. The cell support frame has a first recess in which the liquid crystal display cell is disposed, and a second recess in which the time indicating hands are disposed. An IC chip is mounted on the other side of the circuit board in substantially axial alignment with the display cell, and a wheel train mechanism is disposed on the other side of the base plate in substantially axial alignment with the time indicating hands.
