Abstract:
A liquid crystal display provided with display electrodes disposed in a matrix configuration, said display electrodes serving as pixels, comprising:a substrate comprising thereon an anodic oxidation electrode, and lower electrodes each resembling an island in shape, both of which are composed of a metal film, an insulation film formed on the metal film, two upper electrodes composed of a transparent and electrically conductive film formed on each of the lower electrodes with the insulation film interposed in-between, display electrodes composed of a transparent and electrically conductive film, and signal electrodes composed of a metal film or a metal film and a transparent and electrically conductive film; said two upper electrodes being disposed so as to cross each of the lower electrodes, and constituting two nonlinear resistance elements in combination with the insulation film and the aforesaid lower electrode; said liquid crystal display being characterized in that one of the two upper electrodes constituting the nonlinear resistance elements is connected with the signal electrode, the other with each of the display electrodes; and the display electrodes, serving as pixels, include a first display electrode provided with an overlapping portion having a remaining double layer film thereunder, composed of the same metal film as that composing the lower electrode and the insulation film, and a second display electrode not provided with the overlapping portion.
