Abstract
A liquid crystal display cell of annular form is provided with a central aperture to accommodate an analog time display section having time indicating hands. The annular liquid crystal cell is characterized in that a plurality of common electrodes are provided on one substrate of the cell, to enable multiplexed drive of the display elements of the cell. Each of the plurality of common electrode comprises a plurality of separate common electrode portions which are electrically connected by connecting lead portions. Half of the connecting lead portions can be arranged to be outside the display area of the cell, thereby enabling the available display area to be maximized.
