The present invention relates to a liquid crystal apparatus with a leak current preventing function. In particular, a first invention relates to a liquid crystal apparatus which prevents leak current flowing in a dummy electrode, in a liquid crystal apparatus which has the dummy electrode in order to make uniform a gap between upper and lower transparent substrates in which a liquid crystal layer is inserted therebetween. Further, a second invention relates to a liquid crystal apparatus which prevents leak current flowing in a light-cutting film, in a liquid crystal apparatus in which the light-cutting film is provided on a transparent substrate in order to cut off unnecessary light provided in a liquid crystal unit. A liquid crystal apparatus with leak current preventing function includes first and second transparent substrates provided opposite to each other; first and second drive electrodes for an image, each formed on an opposite inner surface of the first and second transparent substrates; a sealing member () provided between the first and second transparent substrates for providing a liquid crystal injecting area and forming a gap in order to seal the liquid crystal therebetween; a plurality of conductive particles included dispersedly within the sealing member (); a non-pixel electrode formed on position covered by the sealing member between the first and second transparent substrates; a dummy electrode (D) formed opposite to the non-pixel electrode at the position in which the first and second transparent substrates are covered by the sealing member; and a conductive light-cutting film provided to at least one of inner surface of the first and second transparent substrates for cutting off unnecessary light at a display area and peripheral area thereof; wherein the dummy electrode (D) is divided by a plurality of slits, and further, a separation slit is provided at the position at which the light-cutting film is superposed on at least sealing member and peripheral portion, to divide the light-cutting film into a plurality of portions.
