Abstract:
A liquid crystal display comprising:an upper substrate and a lower substrate, wherein at least one of said upper substrate and said lower substrate is a transparent substrate; an upper electrode disposed on the surface of said upper substrate which surface of said upper substrate opposes to said lower substrate, and a lower electrode disposed on the surface of said lower substrate which surface of said lower substrate opposes to said upper substrate, wherein at least one of said upper electrode and lower electrode disposed on said transparent substrate is transparent; a liquid crystal material disposed between said upper electrode and said lower electrode; a scanning electrode line and a signal electrode line disposed on the surface of said lower substrate which surface of said lower substrate opposes to said upper substrate; a switching element for controlling application of a voltages to said lower electrode, wherein said application of a voltage to said lower electrode by said switching element is controlled by application of voltages to said scanning electrode line and said signal electrode line; and a conductive protrusion disposed on the surface of said upper substrate which surface of said upper substrate opposes to said lower substrate, wherein said conductive protrusion is disposed over said scanning electrode line or said signal electrode line and has the same potential as that of said upper electrode.
