Liquid crystal indicator in camera finder

A liquid crystal indicating device for a camera, comprising:

• (a) a liquid crystal cell which includes two base plates facing each other and sandwiching a liquid crystal substance therebetween and a plurality of transparent electrodes outside of each of said plates, the transparent electrodes on the plates forming a plurality of pairs of electrodes opposing each other, and said pairs of electrodes opposing each other being arranged in a matrix and related with other pair or pairs so that any one of the electrodes forming each pair of opposing electrodes is electrically connected with any one of the electrodes forming an adjacent pair of electrodes opposing each other, and
• (b) a driver circuit for applying an alternating voltage of an amplitude above the voltage level for light shuttering of the liquid crystal cell to one of the transparent electrodes positioned at one side of the cell, and for applying a voltage of opposite phase to and of the same amplitude as that of the alternating voltage to one or two of the electrodes positioned at the other side of the cell, so that one or two of the plurality of pairs of electrodes of the cell opposing each other are placed in a light shuttering state, the electrode to which said alternating voltage of amplitude above the voltage level for light shuttering of the light crystal cell is to be impressed being selected so that the one or two pairs of electrodes placed in a light shuttering state are consecutively shifted by one bit each in a direction of the above mentioned matrix corresponding to a change in one direction of an input signal level.
